My older (about 4 years) male cat is showing major aggression to the
younger male in my home(1 1/2 years) . The younger male has been with
me since I took in a stray female who was pregnant, there were no
aggression issue until about 6 monhts ago when my daughter and I
moved. Myself and the older male were staying in the new place while I
did repairs on it and my daughter and the younger male stayed at a
friends. I would bring the younger male over to visit 3-4 times a
week, on one of these visits he viciously attacked the older, much
larger male to the point that he was cowering on top of my fridge and
would not stay in the same room as the younger male.I stopped the
visits for a while. When my daughter and her male moved in to the new
place the older male decieded he was going to contantly attack the
younger one. I am at my wits end on what to do about this, I keep them
seperate now because the younger male was hiding out in the bed room
all the time, no playing at all and I really don't think that is good
for him. Both males have been fixed so I'm not really sure what the
issue is. Also I have 2 fixed females here, one has been with me since
she was born, she is the sister to the younger male, and a stray I
brought home, when I keep the older male away from the younger one
some times he will attack the sister to him, she is very small and I
worry about him huting her. Any ideas would really help. Thanks.
