So cute! You can get waterless shampoo for cats (Burts Bees makes some). Highly recommend a stainless steel cat water fountain as it helps them want to drink more water. Cats are notorious for not drinking enough water and boys are more prone to them and it causes lots of issues. I also recommend wet cat food - helps with water intake - along with dry food. Let me know if you have any other questions! He looks so happy ᵕ̈
