Key Questions

Should I go to the emergency vet?

Straining with no stool, vomiting, or a male cat that may actually be trying to urinate needs the same-day clinic. Stool next to a dirty box in a cat that is otherwise well can be fixed at home and mentioned at the next visit if it continues.

How much will treatment cost?

The exam separates constipation, diarrhea, and a urinary problem that was mistaken for a bowel problem. Films are added when the cat is painful and has not passed stool. Ask for that distinction before you pay for a diet trial.

Can I treat this at home?

Scoop daily, make sure the box is large enough to turn around in, and note whether the stool is hard, soft, or absent. A box upstairs that an arthritic cat will not climb to is a setup problem. Pain still gets an exam.
