- A woman telephoned a veterinarian and asked him to come examine her cat.
"I don't know what's wrong with her," the woman told him.
- "She looks as if she's going to have kittens, but that's impossible. She's never been out of the house except for when I had her on a leash."
The vet examined the cat and said there was no question about her pregnancy.
"But she can't be," protested the woman. "It's impossible."
At that point a large tom cat emerged from under the sofa.
"How about him?" asked the vet.
"Don't be silly," answered the woman. "That's her brother."
Having brought up a female cat and her two brothers, I can tell you that they certainly don't consider blood ties as a prohibition when it comes to "doing what comes naturally".
Mostly, I was able to segregate the boys and girls into separate parts of the house when Kitty came into season the first time, but this merely resulted in the boys all jumping on one another once there was no female present. Even the one who was then seven years old and had been "fixed" when he was a kitten managed to raise interest! Does this make them a "gay pride" too?
