Welcome to PT MARichards! Denyce gave you some excellent advice there. I'll only add that male cats has a tendency to get bladder problems - far from all, but still ...

To avoid it you can feed them food with low contents of Phosfor, Magnesium and Calcium. Hills C/D is one option.

There's no need to feed your cats wet food, they will thrive on dry food, but make sure to let them have access to fresh water at all times.

Good luck with them, looking forward to see pics - if possible.
