I think my cat is going senile. He is now 13 and just doesn't seem to be 'with it' any more. When he looks at me I just get the feeling that there's nothing going on in his head that makes sense. Just a confused stare. A colleague of mine has a cat of the same age, she seems to be the same. So does her cat. Maybe it's normal for this age? I have to go to Milan on business next week and that will mean a spell at the cattery for himself. Will that rattle a senile cat? If he's that senile will he tell the difference?
