My cat tolerant my second pet, who is a cameleon. I have never had any problems wit this kind of connection (reptile + cats). Boston sits in front of the rterrarium and look at Camelon very often, and he makes it too:) I need to send a picture to show you, how does it looks like:)
I have never done like that, but i speak with my cats a lot:) they try to answer me very often. That's crazy, but my cats understands me very well. :) Sorry for my bad english :P
