1/2 of the dynamic Cosmo + Tarzan duo. Cosmo is the valedictorian of smart cat university. He is such a loveable, snuggly, chatty boy, but he is wicked smart. He doesn't like closed doors and the vacuum. He loves catnip, springs, and trying to get himself into trouble. He does have a tendency to develop urinary crystals so he needs to be on a special diet (urinary kibble) which has lots of options both inexpensive and expensive. Does not require a prescription.
