This is making me laugh thinking back to when we had one brought in!
Not the cats, but OH chasing it about, managing to catch it, only for the frog to jump out of his hands
Repeat the above approx 25 times until we finally got it out!!!
It has only happened the once, but I have seen them 'playing' with them in the garden.
I dont know if I would prefer frogs or the mice we regularly get......
