My mom has my cat from when I was a kid because of all her health issues. She will be 17 years old soon and seems to be having a lot of issues lately. She has a wierd growth on her face (i think from the scent glands) that needs popped every month or so, she gets urinary tract infections all the time if she sneaks anything besides her Science Diet, one of her kidneys failed a couple months ago, and now she's not so good with useing the litter box. Wiether she's being defiant or she can't hold her bladder we don't know. The talk of putting her down has come up, but we thinks it's mean to put her down just for a bladder problem. What would someone else do in this situation??
