TL;DR: Feline constipation is a serious condition where stool moves too slowly or becomes stuck; seek immediate veterinary care if your cat hasn't used the litter box for 48 hours or shows signs of pain and vomiting.
What is feline constipation and how does it affect my cat?
Feline constipation occurs when stool moves too slowly through the digestive tract or becomes stuck in the colon. When stool remains in the colon for too long, the body continues to absorb water from it, making the waste hard, dry, and difficult to pass. If your cat hasn't used the litter box in over 48 hours, they are likely experiencing significant discomfort and require intervention.
Is my cat's constipation a veterinary emergency?
- Urgency level: This is a Medium urgency situation; while it may not be a crisis in the first 48 hours, it can escalate quickly.
- Routine Care: If your cat is still eating and acting normally, schedule a veterinary appointment within the next 24 hours.
- Emergency Signs: Seek immediate attention if you notice vomiting, a tense or painful abdomen, or if your cat is straining repeatedly without producing anything, as this may indicate a complete blockage or megacolon.
How does providing a photo or video help with veterinary triage?
- Stool Photos: A photo of your cat's most recent stool allows the vet to assess the level of dehydration and waste consistency.
- Straining Videos: A video of your cat in the litter box helps the vet differentiate between constipation and a life-threatening urinary blockage, as the physical behaviors for both look remarkably similar.
Clinical Context (Merck Veterinary Manual)
In a cat presented with constipation for 48+ hours, physical examination, including abdominal palpation and rectal examination, can confirm the presence of large volumes of retained fecal matter. Plain abdominal radiographs may help establish inciting factors of fecal retention. Affected animals should be adequately hydrated. If enemas are unsuccessful, manual extraction of impacted feces may be needed under anesthesia, with an endotracheal tube in place to prevent aspiration. Phosphate-containing enemas must be avoided in cats. Concurrent fluid and electrolyte abnormalities should also be corrected.
