We lost our Roady to kidney disease. She was 10, but we rescued her as a VERY sick stray kitten in Belgium and weren't sure if she was going to make it initially. She was an indoor/outdoor cat for about 5 years and then we saw the light and made her a very pampered indoor queen of the house. She was very tiny though so her kidneys were not very big and eventually gave out.
I worry about Tiger, Pippin and William because we think their eye problems were due to being sick/exposed to the herpes virus at birth and I just wonder if their immune systems are weaker. I know stress brings out the worst in their health, so we try to keep things as calm as is possible ( how do you do that with 5 rambunctious boy cats in the house!?)
