I agree with Catty1. Take a sample to your vet. It may be a virus or something that is affecting her.

IMHO: Solid Gold is rich food. Rich food can cause upsets. My two females (RB) wouldn't eat it. And Science Diet is junk food labelled as good stuff with the corn ingredients being the junk part.

But, people here swear by SD, so if it works, use it.

Try Innova or Innova EVO. Also Pinnacle or Veterinarian's Formula, all of which can be bought in an independent animal feed store, not the vet's office.
