well we have a common toad and a common frog that we know of that live in the garden, although we dont have a pond or any where really that holds much water other than a bird bath and a water bowl for the wild hedgehog. Must be suitable for them though as they have been here for a few years.
We don't really see any, which is surprising because we are less than a mile away from a massive pond that has loads of toads in it. I would've thought we'd see more passers by and strays, but no
