I’ve had a couple of gay cats, one boy, one girl. Still have the girl. She used to mount the other girls (including her mother) when she and another were both in heat. She’d climb on, bite the neck, and start humpin & pumpin. I could’ve made a video and given it a really sleazy title, see how many downloads it would get. That would’ve been funny.
I have 3 dogs. One large male, fixed. One small male, intact. One female, intact.
Except when the female is in heat, which has resulted in fights between the males despite only one really caring, the small male is submissive to the larger, fixed male.
Laying around side by side and ignoring the female, licking each other all day, they seem pretty gay to me. I just chalk it up to diversity and my tolerance encompasses whatever it is they are getting out of it.
