Sibling Rivalry I have 2 cats - littermates - spayed females about 4 yrs old. Recently they have been fighting alot. They aren't declawed and I am concerned that one or both will get injured. I adopted them at about 9 months and was told they are feral, but they adapted to life in a house very quickly and without apparent stress. Any ideas as to why after all this time they have become enemies - and what I can do to decrease tis behavior? |
