You need to get a life. Seriously.
Hahaha ε=ε=(ノ≧∇≦)ノ
Great thinking but I doubt. He might be asexual and this is just some bromance betweens your male pets.
Even if he ain't interested in the females of your household it doesn't mean he doesn't like females or likes other males.
That’s like my dog Vicster licking my Yuri nendoroid XD
From what you're telling me, he's not just into males, he's into males of other species (dogs, turtles and animated humans). Maybe take him to a psychiatrist? Oh wait.....
YURI ON ICEEEEE
I think my cats gay. He has never shown interest in the female cats and dog in our house but loves our two male pups and my turtle. He’s very extravagant in what he plays with and what he eats and always loves new things. He likes keep himself cleaned up and tidy and likes to chill out in a filled bathtub. He lays over my iPad when I’m watching BL anime and whenever I say Yaoi he meows in reply.
