I have had many cats in my life and I had dealt with their antics at every stage of life.
I have 2 cats, both of which have diva-like attitudes.
The singing at all hours of the night stopped when we brought a new cat friend, Gemini, for our cat Socks, and now she doesn't sing, but rather plan ambushes on Gemini.
I've been scratched by Gemini today.
Well, I have two females, both of which were the only ones for a while in their houses (Socks was an older sister to a younger cat from her mother's second pregnancy, however, that cat died two years ago and Gemini was brought to our house in July 2013, with intentions of staying.)
Yes, I deal with their "catty" behavior.
