I'm sorry to hear that he too has crystals. Hopefully the new diet and clavimox will help him feel better soon. Lots of prayers and positive thoughts are being sent his way.

I have to feed Alani & Blaze a different diet than my other four cats because they don't do well on a grain free diet. Luckily they're already used to eating in the hall bathroom away from the other four. Good luck with the new feeding routine.
