Trampoline

Hi all,
I have an 8ft trampoline for my two buns and I just wanted to make sure will this be okay for them? It is not for living it's just for exercise and they really get hyped and go Binkying around all the time:lol: They go in it a lot and they have never escaped and are always supervised by me or someone else. But is the springy surface okay for them to exercise?
Thanks,
ROLOPOLO

PS. On google images I have seen photos of rabbits on and under trampolines....

It's not something that would have occurred to me to do, personally, but I can't imagine it would be too bad as long as you're supervising. Rabbits aren't heavy enough to get up any real "bounce" so probably couldn't hurt themselves, so long as the springs are covered and they can't get off (and as long as no humans get on there with them!).

No humans are allowed on there with them except to get them out.I was thinking of making them a run underneath with mesh so they have loads of space!
