Can I give my senior cat over-the-counter medicine for diarrhea?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Male | neutered | 14 years and 8 months old | 6.4 lbs

Is there any OTC anti diarrheal that can be given to senior cat? He has been to the vet & honestly they felt he would have passed on by now & thinks he may have a tumor but haven't done anything more than assessing & lab work. Elevated liver enzymes, increased thirst, & very decreased appetite. This started in April & he's lost lots of weight & diarrhea seems worse this weekend. :(

No, there are no over the counter medication safe for cats. You can add probiotics to the diet as this can help. They can be purchased at your vets or pet store. You may want to talk about adding cobalimine to him also. The B vitamins can be lacking with cats with diarrhea and supplementing that can help.
