Hello Debbie  let me start out by saying thank you for adopting a furball
Also  this move is very traumatic on them  it may take a couple days or
longer for the furball to get used to its new  home.   Watch him  if  he
eats  uses the litter box    try  putting both food types out.  But in the
same terms  give him space  and  keep the stress away to allow adjustment

Hi Debbie,

I'm sure he's nervous, but I'd try putting out different foods to see if
you can tempt him. I wouldn't want him to go more than about a day
without eating. Cats can get liver problems pretty quickly when they
don't eat -- I would definitely not wait until next Saturday to go to
the vet if he is not eating!

If other foods are not tempting him -- there is a wet food by Pet Pro
that has sardines in it. I got some at PetCo. Our emergency clinic using
that to tempt scared kitties.

Good luck, let us know what happens!

Rhonda
