Buck, my 8 yr old adopted replacement for my orange cat that passed away in spring, is lashing out behaviorally. I brought home pumpernickel sunday afternoon. Shes a 9 week old tortoiseshell kitten. Buck last evening layed on the couch and pouted a good deal and wouldnt even look at me. Its in the picture below. Hes being a big baby. Then last night he was up meowing and pacing around. This morning he bit at my dog for no apparent reason besides she walked near his spot on the top of the couch. I want to give him extra attention but hes acting like he doesnt want it. Boots, my 12 year old, is quite content and doesnt mind the new kitten. I introduced them last night under supervision and he doesnt love her or hate her. He just could care less. His personality hasnt changed at all. Hes usually very stoic anyways. Im worried about Buck because he has a tendency to pout and hes doing it more since i got Pumpernickel.
