I recently adopted a Siamese mix, Galen, as a companion to my cat Dukhat. Now, Galen gets along extremely well with cats. He and Dukhat are great friends, and they play and chase each other around the house all the time, and follow each other and sleep together. However, Galen is not a fan of humans. He examines us and stares us down, but runs away whenever we get near him or try and pet him. Any tips on how we can get him used to people? Or should we just let him come around on his own?
