I figured it would be ok, I mean the frogs aren't stupid :wink: . They know how to get in and out without getting hurt. I just had a guy tell me once that his frog jumped and missed his target and the spines tore it's skin a little. Probably a rare occurance.
Have you ever watched a lemur hop between Cacti (or some other REALLY spiny plant). It is a type of plant that none of us would even dream of touching. But, the lemurs can hop from 10 feet away, and grasp it without even a scratch. I am sure most of the broms in south and central america have some type of spines. The frogs are definitely not stupid, and are probably very well adapted to these types. I would not worry too much about it. Just my thoughts,
I think the danger of spiny broms is an urban legend. Everyone has "heard" of a frog being impaled but I have yet to hear a first hand account of this happening. Thousands of frogs calling spiny broms sanctuary in the wild can't be wrong.
