Thanks for your help! I called the vet today at 2:30. Paulie is still eating well and acting fine which is really good, I just wish he would use the litter box. I have a ER vet 5 mins from me so if he is acting strange I will run him right there. How long do you think I should wait before I call and check with the vet again. There is another ER vet about 20mins away and they will let you talk to a tech if you have a question which is really helpful. Thanks so much again for your help!
