My cat has terminal kidney failure. There's no cure.

Oh, I am so sorry! I used to have a dog we loved so much who had diabetes...we gave him insulin shots twice a day but we lost him. I can relate to how you feel...

It really sucks. It's fairly common in cats and I sort of knew the diagnosis was coming but that doesn't make it any easier. I'm sorry to hear about your dog.

Our pets are our family...it's not easy to see them suffer..I feel for you. And thank you about our dog.
