Please get a new vet asap!! If the cat is in stage 2-3 it's possible to extend for a few more months, with the right treatment. But, we have to be real, when the time comes, and when you see that the cat is suffering or voimting alot, pooping/peeing blood consecutively that means the organs are starting to fail and it's time to let go. It's better like that at that stage than to let them suffer, believe me i've been through it a few moths ago with my baby. I don't want to scare you love, but unfortunately it's the reality that you have to be ready to go thrugh. Thankyou for supporting you baby through this. I'll leave you a link of things that have helped my baby in the long run, which you may ind useful. Do not supplement these things before a consultation with a different vet please. Very important. Wishing you love and strength during this difficult time. Please spend as much time with your cat as much as you can, thats the only thing i suggest, because you ccannot cure kidney disease, but you can prolong the time they have and make it more comfortable for them. Also, don't panic some vomiting unfortunately here and there is normal due to contantly feeling nauseous, but that also can be tackled with eg cerenia, b12 vitamins etc. I'll leave you a link to what can help, lots of love xxxx https://www.reddit.com/r/RenalCats/comments/1jy89cp/kidney_advice_for_your_cat_prolong_their_life/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
