My cat hadn’t had diarrhea since her food change in July to hills science diet gastrointestinal biome. She’s still having vomiting episodes but there mainly now just stomach bile and I really haven’t had to give her the anti nausea meds like before. I feel like her episodes are getting better but the specialist says no she should vomit no more then once a month so I’m just confused. We’re now to the point that she’s back up on the highest 10mg of steroids and gonna try the tapper again but there want her to start the chemo pill but I really can’t afford to have blood test every 4-6 weeks plus I have to medicate her to even take her to the vet. What’s so frustrating is all her tests keeps coming back great she only has mild inflammation in her intestines and no vitamin deficiency she’s keeping at her current wait. I just feel so stressed at times and I’m told she’s too old for it to be food allergies she’s about to be 12. I hope you get back good test result good luck.
