My boy was neutered about three months ago. My girl isn't yet spayed although she will be very soon. They live next to each other, separated by wire mesh and sometimes go out in the garden together or in the shed. They get on fine although my boy is still "humping like crazy"! She lets him and makes funny little squeaking noises (like a guinea pig). I know she is obviously still hormonal but will he stop mounting her when she's spayed or could he still act like this? It's him thats doing all the chasing and mounting. I just want to know if it's the fact that she's not yet spayed that's causing him to be like this or is he always going to be like this even though he's been neutered. Any advice would be greatly appreciated.
