# Cat Constipation: What Should You Do?


## Key Takeaways

- Constipation in felines can stem from multifactorial causes including dehydration, excessive hair ingestion, pain (e.g., from arthritis impacting litter box posture), dietary indiscretion, or underlying chronic conditions like megacolon.
- At-home management should prioritize environmental calming, a thorough assessment of basic physiological parameters (appetite, hydration, energy), removal of potential toxins or foreign bodies, and meticulous record-keeping of symptom onset and progression.
- Emergency veterinary intervention is critical for cats exhibiting dyspnea, collapse, seizures, severe weakness, repeated vomiting, hematochezia, abdominal distension, profound pain, anorexia, anuria, or any rapidly deteriorating clinical signs, particularly in vulnerable life stages or immunocompromised individuals.
- Diagnostic workup by a veterinarian will typically involve a detailed history, physical examination, and may extend to laboratory analyses (hematology, serum biochemistry), urinalysis, fecal cytology, and radiographic imaging to elucidate the underlying etiology.
- Proactive risk reduction strategies focus on promoting adequate water intake and prompt veterinary consultation if constipation persists, appetite diminishes, or emesis develops.

**Constipation in a cat can be mild or serious depending on the pattern, timing, and other signs. It may involve local irritation, discomfort, stress, injury, stomach upset, skin changes, or another medical problem. Call your veterinarian when signs are persistent, severe, or worsening.**

## What symptoms or causes should I watch for?

- **Dehydration:** Low fluid intake can harden stool.
- **Hair ingestion:** Hair can contribute to stool changes.
- **Pain:** Arthritis can make box posture difficult.
- **Diet:** Diet changes can affect stool.
- **Megacolon or disease:** Some cats develop chronic colon problems.

## What can I safely do at home right now?

- **Keep your pet calm:** Use a quiet room and limit rough activity until you know what is happening.
- **Check the basics:** Look for appetite changes, water intake, bathroom habits, breathing, pain, and energy level.
- **Remove obvious risks:** Pick up unsafe food, plants, medication, trash, string, toys, or chemicals.
- **Record details:** Write down when it started, how often it happens, and what changed recently.
- **Call your vet:** A cat owner should ask for guidance if the sign continues or the pet seems unwell.

## When is this an emergency?

Go to an emergency veterinary clinic now if you notice:

- Trouble breathing, collapse, seizures, or severe weakness.
- Repeated vomiting, severe diarrhea, blood, or a swollen belly.
- Obvious pain, inability to walk normally, or crying when touched.
- Not eating, not drinking, or not urinating normally.
- Any rapidly worsening sign, especially in a puppy, kitten, senior pet, or chronically ill pet.

## What will my veterinarian check?

Your veterinarian will use the history and physical exam to narrow the cause. They may recommend lab work, urine testing, stool testing, imaging, skin or ear tests, or other diagnostics based on the sign.

## How can I reduce the risk next time?

Encourage water intake and seek care if straining continues, appetite drops, or vomiting starts.
