I know this is a sensitive subject with all pet owners, and it is with me right now because I have a beloved kitty of my own that is having health issues.
At 11 years, your cat is considered a senior cat. How is he doing otherwise in terms of heath issues? How is his overall quality of life? Is it deteriorating or holding steady? Are the urinary issues the only problems, or is there more going on?
The reason I ask is because, sometimes when older pets start having health issues, and the bills start running high, we need to start evaluating what is really best for the pet. Sometimes it's best to let the pet go, even though that is really hard on us, the pet owner.
I've gone through before with my first cat. She had lots of urinary issues and finally developed cancer. She was just miserable. we could have spent thousands of dollars on meds and treatments with no guarantee, but we made the difficult decision to put her down. Our thought was, why put her through more misery when the outcome was unclear? She had led s good life, and had been with us for 15 years.
I'm in the process now of having to make the decision about 11 year old cat that we adopted 3 years ago. It's hard. I want more time with her, but is it really fair to her to let her suffer?
I understand your feeling of letting your cat down, but maybe the time has come? I don't know, I'm not with you and your cat, and I'm not a vet. But it may be time to broach the subject with the vet.
I am so sorry if i have upset you or offended you because that was not my intent. I hope all goes well with your cat. I know how important pets are, really I do.
Best wishes for you.
