I am new to this forum but not new to cats. Currently I have a four year old male who I bottle fed and is spoiled and fat. This past year I acquired 4 more cats . All strays and now fixed and tamed and part of my home. A problem has developed between my orginal cat and one of the new male cats. They have a problem with getting along. They can't be in the same room together without fighting. So I have to keep them separated. All the others get along fine. This has been going on a year now. Any suggestions would be greatly appreciated.
