My girls are beginning to act pretty strange since Jello, the ShihTzu, came to live here. I've made sure the cats are fed first, petted first when I get home, playtime is the same...as a matter of fact, it is only when they are napping that the dog gets my full attention. Well, QT has decided that the dog's crate is her sleeping quarters now.Jello doesn't mind though. Skinny makes the dog whine because she will be friendly and willing to play but suddenly she either slaps him with her paw or gives him the cold shoulder. Joji meows so loud when she sees him that I think she's in for a bad case of laryngitis.Jello is deaf to it, but I am not! Is this behavior normal? None of the girls show sign of aggression like hairs standing on end, or hissing, or claws out (not that please!)...just this weirdness. Should I be worried?
