Oh Karen. We've been through this with Smoky our beloved Manx. When the vet told us he was in pain and struggling to pee, we ( keeley and I) made the decision to put him to sleep. I had to do the same thing with Mo. Thousands of dollars in vets' bills but hey, it's only money. And if I hadn't spent it on keeping my cats alive, I probably would have spent it on something else. I've never had money in the bank so I'm used to being poor. Keeley has spent multiple thousands on Phoenix and she wouldn't have it any other way. You'd spend that on your children if they were sick, wouldn't you? And people who say why do you spend so much on your pet have no idea what love is!
