My young cat has diarrhea after spay/vaccines. How can I help her?
I'm glad that Nymeria isn't feeling lousy as a result of her diarrhea! Since it has been two weeks since her vaccines and spay surgery, I doubt that they are related to her current issues.
A few causes of diarrhea can include parasites, stomach upset from diet, viruses, etc. If she hasn't had a recent fecal examination, I would call her regular vet about having a stool sample analyzed for the presence of parasites. Try changing her diet to a different protein source (e.g. chicken instead of fish) and avoid treats, table scraps, or dairy products since cats are lactose intolerant. Adding a probiotic, such as FortiFlora, to the diet can help some cases of diarrhea. Call your vet in a few days if the diarrhea persists, or if Nymeria begins vomiting or stops eating at any point.
