Please, any advice or opinions are welcome - preferably from someone who has either experienced euthanizing their cat, or has had the choice. Long story short, our cat was suddenly diagnosed with cancer 48 hours ago and told we should put him down tomorrow. Obviously this is a huge shock but the vet seems to think it’s best we euthanize. It’s kidney cancer, now lymphoma, he’s been on antibiotics/anti-sickness & painkiller Vetergesic (anyone know this?) for 2-3 days now. He is lethargic, not moving all day, lying still but not closing eyes - eyes are wide open and staring into space (is this the painkiller? Or cancer? We don’t know), but the worst concern is that he is unable to eat.. he hasn’t eaten anything in 2 whole days now and before that, was having about 3 chunks of meat for a few days. We are worried he will starve to death if we don’t euthanize him and the vet recommended it due to his complete change in personality (he’s usually so interested in everything and cuddly, and he’s just staring straight completely not phased by anything even his treats or brother), and his weakness in his body, along with the fact that his cancer has spread everywhere. But saying this, he isn’t struggling or seems to be suffering at all visually. He is just lying there eyes open, but not actively suffering? Help????
