We have 6 cats! It was not really planned, but it happened.
When my wife and I started dating, she had 4 cats and I had a dog. Due to the nature of our romance, I had to get rid of the dog when she started digging under the fence (she was a pound rescue and I found a very good home for her - our neighbors behind us).
Then one of her cats, her favorite, died. She was really upset about it. So we went looking for another white cat. (Sparky was white as were 2 of the other 3. The fourth was black and white.) I did not realize that you had to be interviewed for cats! But we searched pounds and the classifieds and could not find one.
Then one day, she checked the pound in her county. No white cats. But 3 Mary kittens that were about to be put down. Her heart would not let that happen, so I acquired 3 Mary kittens! (we still had separate houses).
As our romance grew and we were wed, we knew we had to combine the households. So we introduced the cats. Her 3 males, and my 2 females and 1 male. Eventually, they all moved in at our house.
So OK, the 3 males had pretty much grown up together and they either played or tolerated each other. My 3 kittens grew into Cats and since they knew each other from the womb, always got along, although each had their own personality (and we named them very well!).
But now they were a family of 6 cats! At first, they were 2 factions. Wary of each other, but middling tolerant of each other. But over the years (3 now), things started to change. The loving Himalayan always like to play with the black cat. But the black cat was getting old and was tiring of cat play. So in steps the male Mary cat! And they became best of buds!
The non-Himalayan white has always been a real bastard! Never wanted to have anything to do with anyone or any cat! But the runt of the Mary's was always a little imp! And so they bonded and now are best of Buds! So much so that the Himalayan and the runt always fight (and the Himalayan is the sweetest of the 6!).
And grandpa? The Black cat (he is now about 10)? Does he love the biggest female Mary? In a way. They both compete for the spot between my wife and I! Sibling rivalry on display!
So the 2 families are now the Brady bunch! But it is not Marsha, Jan and Cindy against Greg, Peter and Bobby! It is Bobby and Cindy against Peter and Jan, and Marsha and Greg ignoring the rest of them! And vying for the most loving cat!
My house is now a cat house Peyton place!
Cat's are weird!
