I rubbed a young female kitten's genitalia out of curiosity
Why did you feel it was okay to fondle a kitten?
I was just curious, I'd asked about animal genitals several times before.
Although curiosity is a normal part of life, you should not bother a cat by touching it's genitals. It is unkind to the cat and could make the cat claw you. You should read a science book to satisfy your curiosity.
You are right. It was stupid to touch her.
It's great that you are able to understand the mistake that was made. It's important to respect private areas of all animals.
