BTW - I was reading about these frogs and I don't think it is much of a concern for humans, but if you have a dog or cat, it may be - the skin secretes a hormone that will slow down the heart rate and cause nausea in mammals.
I wasn't aware of that fact, thank you for the warning. I actually have four cats, and three dogs. But, only the one dog comes into my room, and she couldn't be bothered by the frogs. The River Frogs are quite tame, because I raised them from tads. I will definitely be cautious though.

May I ask if you have read 'Frogs and Toads of the World', by Bounty Books? It is a very interesting general text.
