My cat stopped eating or interacting with anyone including our other cat although they got along extremely well. She just sits in the same isolated spot and only drinks water. She lost a lot of weight and looks very weak. We took her to a vet and blood tests revealed that everything is normal. We are currently force feeding her but its been almost 10 days and nothing is changing . What should i do? I am really desperate since vets aren't helping so any advice would be appreciated.
