After the latest vet gave her subQ, I tried feeding my cat some yoghurt(just milk and probiotics and I am aware that there is high calcium in it, which isn't great for the kidneys), with the dry food to increase her water intake and get probiotics, since she wasn't drinking any. And after doing that it helped, she was feeling better for a few weeks and started drinking much more water but then she stopped wanting yoghurt. So going back to the exclusively dry renal food, she is now vomiting every time I give her that(except if I introduce chicken breast into her diet) When I give her boiled chicken breast, she becomes super excited and happy. She She hasn't vomited when I give her chicken breast. When I told the vet who did the surgery that I am feeding her chicken breast, he went crazy and said it's very bad because the proteins in the chicken breast aren't digestible while the one in the dry food is. If you ask me if the cat isnt eating anything and is vomiting some other food, chicken breast is better than nothing but this vet thinks otherwise. He recommended an overnight IV with steroids, but my cat hates going to the vet and I cant imagine the stress of having her stay at the vets. As of today, the gum infection hasn't been treated properly and the CKD is just there, and I have no idea what to do anymore. It is really exhausting. I would really appreciate some insight into how I can move forward.
Question 1: How bad is boiled chicken breast for a cat with CKD, and in circumstances in which she isn't eating anything else?
Question 2: Is there another way to feed the cat probiotics in a form that the cat would be willing to consume it, if not yoghurt?
Question 3: If a cat with CKD isn't drinking plenty of fluids, wouldn't a diet exclusively composed of dry food exacerbate the kidneys?
Question 4: The course of events almost suggests that the gum disease caused CKD, perhaps through limiting water consumption due to pain when drinking and general infection. Is there research that supports this hypothesis?
Question 5: What is causing the cat to sometimes vomit the dry food? If it's stomach acid, then isn't the food designed to counter that by pH control?
