Hello,
I’m so sorry to hear about your cat. And all of the others in his situation.
I do not have any experience with apple cider and honestly I am too worried about what is likely already going on with your cat to try to advise anything else other then the er.
I’m working really hard to accumulate a list of affordable places and options. Please let me know if you find anyone locally. Please keep calling everyone and everywhere.
If all else fails offer to surrender your cat to get the care he needs. I know it’s not fair but it’s better to save his life.
Keep me appraised of what happens.
Best of luck
Hello
These are often complicated issues involving multiple underlying things. To include diet, litter and litter box dislikes and environmental stress. I would look for a vet who specializes in feline medicine and place different kinds of litter boxes and litter types for your cat. Also make the area your cat lives in is as free of stress as possible. Calm quiet and easy to access all of the things she needs. Like fresh high quality canned food. Fresh water. And immaculately clean litter boxes. Also I add an anti inflammatory like dasaquin and a pain medication. I like gabapentin but your vet might use something else. Also ask about learning how to give sq fluids at home. Follow up with a urinalysis too.
Good luck
