Is perlite toxic to red eyed tree frogs?

If there are fertilizers in the substrate, then yes, it would be toxic. Perlite if accidentally ingested can cause an intestinal obstruction.

Sorry for your loss.

Perlite is inert and non toxic but it is an impaction risk as mentioned and should be taken out. Anything in the cage that's small enough to be swallowed needs to be small enough or soft enough to easily pass through the frog.

i tend to disagree a bit here Heather. it really depends on the fertilizer. something like worm castings or bat guano (or i could name more..LOL) are all natural and have chemical compounds in them that the frogs frequently encounter on a daily basis in the wild. but those fertz they put in stuff like Miracle gro, i would agree, very toxic. but not from the actual chemical compound of the fert, it's the binding agents they use that are severely toxic to animals.
