Are you thinking about bringing another cat home to be a friend to your cat, dog or other pet? We found out the hard way that you can’t just put the new cat in front of the others and expect them to sniff and hiss it out in order to become friends. If you do this both animals will likely have behavior problems ranging from marking territory throughout your house to fighting or increased aggression. The worst part is, once a cat starts marking in an area, its difficult to get them to stop. The most heart breaking experience I had was to be forced to find separate homes for my two cats because I couldn’t get them to stop marking and their behaviors became aggressive.
