We all know animals do things that at first may seem to have no reason like when your dog drags its butt across the carpet but in fact it has a purpose like a cat eating grass and other odd things we may see like a cow eating the after-birth from a calf she may of just had or even another cow joining in on the feast these things all have a definite reason so if animals display what may seem to be homosexual behavior it serves a purpose other than the animal likes a same sex partner it is serving a purpose and filling a need, perhaps like a group of females living together so no single male can have his way with each one, or to protect a female who is not ready to mate or other options to be sure all the young are conceived and born and raised at the prime time not because they are a group of butch females.Don't forget that until modern times when people who had made the choice to be gay, humans made a deliberate effort to conceal that choice (that's a human trait) apparently animals don't try to hide things that are required to keep living HOMO-sexuality is a HOMO-sapien thing connected with sexual desire, human thinking and a soul which most people believe animals don't have
