Only keep them if you will let them inside
They are inside tm, we set up home for them upstairs and have the two girl kitties that we own, downstairs....but they are pushing their way in to the downstairs area....there is a door inbetween but every time i try to go upstairs they push through and get in to the downstairs living area with my other two cats....some screaming and yelling by my elder cat and some slight fur flying from swatting that took place, but the elder cat seemed to settle down...
.the alpha cat, Brodey, just sat there for 2 hours without moving, trying to stare my elder cat down....my elder cat was cat growling the whole time but the last half an hour, she ended up just turning her head and then falling asleep in her bed, with the male cat still in here....
She handled it much better than I thought she would.....she nearly KILLED Casey, the girl stray we took in last year....and it took the year, before they actually came to just 'tolerate' each other. Now, my elder cat and Casey are getting along like best buddies, it is the two girls against the two newbie boys....
miracles happen!
