I have just takeing in one of my grandkitties from my daughter . The 2 adults here already and the new additon all have very different personalities. Winky (the old guy 14 yrs) Knew him (moose the new addition) as a kitten and just looked at him and said Oh no your back. (another story all to geather) The 3 year old female Ebby is still slinking around and hissing. Moose of course thinks he owns the place (at 16 lbs he doses generally get his way. The others are about 5lbs. ) I figure this winter when every one has to be in the house is when we will have the problems.
Yes I let them outside , I have a fenced yard and a lot of sr apartments that do not allow pets (so some one always comes home smelling of tuna) I have even been calling the kids in at night and had one of the sr. ask if the cat could stay to visit longer . I had to put a sign up in their landury room with pics telling them the kids have to be home by 9pm for dinner and be in for the night.
I say get another kitty .
