Over the past couple of days my usually playfull cat has been virtually nonsocial. Petey has been biding his time under the bed (he normally sleeps with me) He has hardly eaten anything and he meows when he walks around the litter box. I've also cleaned discharge from the inside of his eyes. I will be taking him to the vet in the morning, should I be concerned? Do cats catch colds? Again this just started within the last couple of days.
