No, CJ is not having problems, calm down Barbara.

Tubby never ever had any problems such as stones and/or crystals. All he ever had was a UTI once when he was about 17 (if I remember right). However, it does seem to be somewhat of a common problem for male cats, and age doesn't seem to be a factor, so I was wondering.....

If CJ is eating Science Diet Senior formula, is this a good food to help prevent such problems? I guess I'm thinking it is because of never having problems with Tubby, but I'm just curious. I know there are certain foods out there that kitties need to eat to help prevent this, but if he hasn't had any problems....

Like I said, he's had no problems peeing (and 3 days in a row now for first class, a-1's ) but as you can imagine after everything I've been through in the last two months, I'd really rather take preventative measures rather than end up at the emergency vet again.

Are there any foods/treats I should stay away from that are more likely to cause stones/crystals?

Thanks for all the advice!
