Found cat has swollen stomach, constipated. What should I do?
Hi Taylor! I'm very glad that you found Lily, what a relief for you! Likely, her stomach problem is related to intestinal worms. That would cause her constipation and a swollen stomach. Lily will need a deworming treatment as soon as possible. I recommend Drontal, which is available by prescription only from the vet. Drontal is my recommendation for Lily because she could also have tapeworms from being outside so long, and OTC deworming treatments do not contain the medication needed to kill tapeworms. In addition, after being missing for so long, she will need a check up from the vet to make sure she is healthy, and the vet can prescribe her the Drontal while at the visit. I would have Lily seen by a vet tomorrow for a health check and Drontal. Tonight, you can give her a teaspoon of canned pumpkin puree (not pumpkin pie filling) mixed in with her food to see if that helps her poop. Please have her seen by a vet first thing in the morning.
