My cat leaves the frogs alone. She does not however leave my son's lizard alone. I have taught my cat not to get on the tops of my tables by flicking her nose. I only had to do it a few times. She never climbs on my tanks, tables or counters anymore and even leaves my fish alone. The few times my escape artist frog got loose she followed him around but never tried to eat him. I am very glad of that considering I have heard whites tree frogs can be toxic to dogs and cats. The clamps that go on the lid have been a life saver. Frogger never excapes anymore.
