# FHO Cat Physical Therapy: Exercises and Recovery FHO cat physical therapy is a structured program of gentle, vet-guided exercises that starts within days of femoral head ostectomy surgery and continues for several weeks. The goal is to rebuild muscle, restore comfortable movement, and help your cat walk normally again. Most cats do best with short, frequent sessions at home plus rechecks with your veterinarian. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - FHO removes the femoral head and neck so a false joint can form from scar tissue, and physical therapy helps that new joint work well. - Start with passive range-of-motion and cold therapy in the first days after surgery, once your vet clears you to begin. - Keep sessions short. Cats lose interest and get frustrated quickly, so several brief sessions beat one long one [1][2]. - Expect noticeable improvement over 4 to 8 weeks, but full strength and gait symmetry can take months. - Call your vet right away for swelling, heat, discharge, sudden pain, or a cat that stops using the leg. ## What FHO Surgery Is and Why Cats Need It Femoral head ostectomy, often called FHO, is a surgery that removes the ball portion of the hip joint (the femoral head) and the neck of the femur. The socket stays in place. Without the ball rubbing against the socket, the source of pain from a damaged hip is gone. After surgery, your cat's body builds a cushion of scar tissue where the joint used to be. Muscles around the hip then act as a sling that supports the leg. This is sometimes called a false joint or pseudoarthrosis. It is not a real joint, but it can work well enough for normal activity. Vets recommend FHO most often for cats with hip problems that cause ongoing pain, such as a fractured femoral head or neck, hip dysplasia, or severe arthritis. The procedure is also used when other options are not a good fit for a particular cat. One thing to know up front: even cats that recover well may not put quite as much weight on the operated leg as on the other legs. A study that measured ground reaction forces in cats at least one year after FHO found lower force on the operated limb compared with the other limbs and with healthy cats [3]. Owner questionnaires in that same group were generally good, which tells you that cats can function comfortably even when measurements are not perfectly even [3]. Cats that had a total hip replacement instead showed more even weight bearing between the hindlimbs [4]. That does not mean FHO is a poor choice. It means your expectations should be realistic. ## How to Prepare for FHO Cat Physical Therapy Preparation starts before your cat comes home. Ask your veterinary team these questions while your cat is still at the clinic. - When can I start touching and moving the leg? - Which exercises do you want me to do, and how many repetitions? - How often should I do them each day? - What pain medication is prescribed, and how do I give it? - When is the first recheck? Pain control matters for recovery. Relieving pain is an important part of treating lame animals and may allow faster recovery, so follow all medication directions exactly as prescribed [5]. If your cat is painful, exercises will be harder and your cat will resist them. Set up a recovery space before your cat comes home. A small room or a large crate with soft bedding limits jumping and climbing. Put food, water, and a litter box within easy reach so your cat does not have to travel far. A low-sided litter box helps a cat with a sore hind leg. If your cat takes joint supplements, ask your vet whether to continue them during recovery. You can read more about options in our article on [Cat Joint Health Supplements](/knowledge/veterinary-medicine/veterinary-technology/cat-joint-health-supplements). ## What Happens During FHO Cat Physical Therapy Rehabilitation for cats uses a mix of hands-on techniques and active exercises. Your veterinarian or a rehabilitation professional will choose what fits your cat. Cats are not used to regular handling and restraint, and they tend to become uninterested and frustrated quickly, which is why many people assume cats are poor candidates for physical therapy [1][2]. That view is changing as more evidence shows cats benefit as much as dogs do [1][2]. ### Passive Range of Motion Your vet or technician may show you how to gently flex and extend the hip while your cat lies on her side. You support the leg and move it through a comfortable arc. This keeps the tissues flexible and helps prevent stiffness. Stop if your cat tenses, pulls away, or vocalizes. ### Cold and Heat Therapy Cold packs reduce swelling and pain in the first days after surgery. Heat can relax tight muscles later in recovery. Your vet will tell you which to use and when. Always wrap packs in a cloth so they never touch skin directly. ### Massage and Gentle Stretching Light massage of the thigh and hip muscles helps circulation and keeps tissues supple. Stretching should be slow and within your cat's comfort range. Never force a limb. ### Active Exercises As healing progresses, you can encourage your cat to move the leg on her own. - Slow leash walks or guided walks around a quiet room - Tempting your cat to step over a low, stable object - Placing treats so your cat has to shift weight or take a few steps - Using a food puzzle or a toy that encourages standing and reaching Weight shifting and controlled stepping build the muscles that will support the new false joint. Keep surfaces non-slip. Rugs or yoga mats help a cat feel secure. ### Underwater Treadmill and Other Clinic Therapies Some clinics offer underwater treadmills and other professional therapies. These let a cat walk with less weight on the legs. Ask whether your cat is a candidate and whether the clinic has experience with feline patients. If your cat had a complicated surgery or nerve involvement, rehabilitation may be part of a longer plan. One report described a cat with sciatic nerve problems after FHO who needed surgery to free the nerve, followed by six weeks of limited activity and rehabilitation treatments to support an excellent recovery [6]. Cases like that are uncommon, but they show why rechecks matter. ## FHO Cat Recovery Timeline and Home Care Every cat heals at a different pace. The table below shows typical milestones. Your veterinarian will adjust the plan for your cat. | Time After Surgery | What You Will Likely See | What to Do | |---|---|---| | Days 1 to 3 | Sleepy, sore, may not use the leg at all | Confine to a small space, give pain meds as prescribed, cold therapy if your vet approves | | Days 4 to 10 | Starting to bear some weight, taking a few steps | Begin passive range-of-motion and gentle massage if cleared, keep activity restricted | | Weeks 2 to 4 | Walking short distances, using the leg more | Add guided walks and easy active exercises, continue pain control as directed | | Weeks 4 to 8 | Steadier gait, jumping less than before | Increase activity gradually, keep non-slip surfaces, attend rechecks | | Weeks 8 to 12 | Near-normal movement for many cats | Build strength with play and controlled exercise | | 3 to 12 months | Continued slow improvement in muscle and gait | Maintain activity, watch for limping or stiffness | A few points about this timeline. Improvement after FHO can continue for many months, and some cats never fully even out their weight bearing [3][4]. That is expected. What matters most is comfort and function in daily life. Owner-reported recovery measures are often used in cats because cats cannot tell us how they feel, and these reports focus on function and comfort instead of x-ray findings [7]. Home care rules that apply throughout recovery: - Follow your vet's activity restrictions exactly. Too much movement too soon can slow healing. - Give all medications on schedule. Do not skip doses because your cat seems better. - Keep the incision clean and dry. Check it daily. - Use non-slip flooring everywhere your cat walks. - Keep other pets and children from bumping or chasing your cat. - Weigh your cat or ask the clinic to weigh her at rechecks. Muscle loss is common after limb surgery and is easier to catch with numbers. If your cat has had other surgeries, some of the same recovery principles apply. Our guide to [Cat Spay Recovery](/knowledge/veterinary-medicine/preventive-care/cat-spay-recovery) covers confinement and incision care in more detail. If your cat limps after a jump before or after surgery, it can be hard to tell a minor strain from a fracture. This article explains the difference: [Cat Limping After a Jump: Is It a Sprain or a Break?](/knowledge/veterinary-medicine/vet-visit-decisions/cat-limping-after-jump). ## Possible Complications and Warning Signs FHO is a common procedure, but complications can happen. Watch for these problems. - Swelling, redness, or heat at the incision - Discharge or a bad smell from the surgical site - Bleeding that does not stop - Sudden increase in pain or crying when touched - Your cat stops eating or drinking - Your cat stops using the leg after previously using it - Fever, lethargy, or hiding more than usual - Weakness or dragging of the paw, which can point to nerve irritation Nerve problems are uncommon but possible. In one reported case, a cat developed sciatic nerve dysfunction after FHO, with muscle wasting and reduced sensation in the limb [6]. That cat needed further surgery and a long rehabilitation period [6]. If you notice your cat dragging the top of the paw or losing feeling in the leg, call your vet promptly. Some cats also develop muscle atrophy around the hip over the long term. A study in dogs found muscle loss and reduced weight bearing on the operated limb years after FHO, even though most owners reported normal activity levels [8]. Cats show similar patterns of slightly uneven weight bearing after FHO [3][4]. Physical therapy is one of the main tools to limit muscle loss. ## Questions to Ask Your Veterinarian Bring this list to your next appointment. - Which specific exercises should I do, and how many times per day? - How long should each session last? - What should I do if my cat resists or seems painful? - When can my cat resume jumping and climbing? - When is the next recheck, and what will you assess? - Do you recommend a referral to a rehabilitation specialist? - What is the plan if my cat is not improving as expected? Your vet may also adjust medications over time. Pain-relieving drugs, supplements, and other techniques are all used to control pain in lame animals, and your veterinarian is the best person to choose the right treatment for your pet [5]. Never give human pain medications to a cat unless your vet specifically prescribes them. ## Limitations and When to Contact a Veterinarian Physical therapy helps many cats after FHO, but it cannot fix every problem. Some cats have nerve damage, infection, or other issues that need medical or surgical treatment. Rehabilitation research in cats is still growing, and the best protocol for each cat is not fully settled in veterinary research [1][2]. Your veterinarian will tailor the plan to your cat's age, weight, other health conditions, and surgery details. Individual cases always need a veterinarian's assessment. Contact your veterinarian the same day if you see: - Increased swelling, redness, or discharge at the incision - A sudden change in how much your cat uses the leg - Pain that seems worse than in the first days after surgery - Your cat refusing food or acting dull - Any concern that the incision has opened Go to an emergency clinic right away if: - Your cat is bleeding heavily from the surgical site - Your cat cannot breathe normally or collapses - Your cat cries out in severe pain that does not ease - Your cat's leg looks deformed or suddenly gives way Call for a routine visit if: - Your cat is not improving after several weeks of therapy - You are unsure whether you are doing an exercise correctly - Your cat seems stiff or sore after activity - You need a medication refill or a therapy plan update ## Frequently Asked Questions ### How soon after FHO surgery can I start physical therapy? Most cats can begin gentle passive range-of-motion and cold therapy within the first few days, but only once your veterinarian says it is safe. Some vets prefer to wait until the first recheck. Never start exercises on your own before your cat's surgical team clears you. ### How long does full recovery take after FHO in cats? Many cats show clear improvement within 4 to 8 weeks, and function can keep improving for several months. Measurements taken at least a year after surgery show that some cats still carry slightly less weight on the operated leg [3]. Comfort and daily function matter more than perfect symmetry. ### Can I do physical therapy at home, or does my cat need a specialist? Many cats do well with a home program taught by their veterinarian. Cats get bored and frustrated with long handling sessions, so short and frequent works best [1][2]. If your cat has nerve problems, severe muscle loss, or is not progressing, ask about a referral to a rehabilitation professional. ### Will my cat need pain medication during recovery? Most cats go home with pain medication, and relieving pain may allow faster recovery [5]. Your veterinarian calculates the dose from your cat's weight and health, so never adjust it yourself. Call the clinic if you think the medication is not working well enough. ### What if my cat refuses to do the exercises? Stop and try again later in a calmer moment. Cats often resist when they are painful, tired, or stressed, so a refusal can be useful information. If your cat consistently refuses, call your veterinarian to check for pain or another problem before pushing further. ## Related Articles - [Cat Spay Recovery](/knowledge/veterinary-medicine/preventive-care/cat-spay-recovery) - [Cat Limping After a Jump: Is It a Sprain or a Break?](/knowledge/veterinary-medicine/vet-visit-decisions/cat-limping-after-jump) - [Cat Joint Health Supplements](/knowledge/veterinary-medicine/veterinary-technology/cat-joint-health-supplements) - [Fluid Therapy Guidelines for Dogs and Cats: A Practical Update](/knowledge/veterinary-medicine/emergency-critical-care/fluid-therapy-guidelines-dogs-cats-practical-update) - [Radiographic Assessment of Fracture Healing in Dogs and Cats](/knowledge/veterinary-medicine/diagnostic-imaging/radiographic-assessment-fracture-healing-dogs-cats) - [Cat Physical Therapy: Exercises for Back Legs and Mobility](/knowledge/veterinary-medicine/senior-and-chronic-care/cat-physical-therapy-exercises) - [TPLO Surgery Recovery in Cats: Week by Week](/knowledge/veterinary-medicine/vet-visit-decisions/tplo-surgery-cat-recovery) - [Cat After Surgery: Recovery, Cone Care and Warning Signs](/knowledge/veterinary-medicine/vet-visit-decisions/cat-after-surgery-recovery-care) ## References 1.
