HI I'm very new to owning guinea pigs. I've had my guinea pigs Enzo and Leo for about 3 months now. Enzo is doing fine and is super active and happy. Leo is a different story, He always sits in a corner or his hides hole and does nothing. He only comes for food and water. They recently had Ringworm but we cured it, I want to know if there was any way we could make him more happy and more out there. He loves Enzo and talks to him a lot, but He never plays with Enzo. Any tips or help?
