Pets responding to image in a mirror

[Catherine]

That is sweet about the goose.
Misty and Puce were both too smart to fall for a mirror. Sally cat being a typical cat is going to act aloof so you will never be sure what she thinks.
Forgy is obviously too clever to fall for a mirror even once.

Reptiles? Most lizards will react with their reflection in the glass. A mirror would drive them  wild.
Bearded dragons are the worst. The males are forever thinking they see another dragon and reacting to it.

Snakes wouldn't see a mirror. The glass is cold so they would not react at all. They respond to heat and scent. If I have food scent on my hand I will get bitten. The snake will let go right away when it realizes I am not food.  Snakes see heat so a heat source will attract a snake where an image will not. I was holding a green tree python, Mr. Green, a very gentle creature. We had a small lit candle on the table and he "saw" it as small and hot and therefore probably food. He struck at it as if he could eat it. Fortunately the flame went out, but he got hot wax all over his face and in his mouth. WE were able to clean him up and he was fine, but he was confused. He was sure he "saw" food.

I don't  know if a turtle would react to a mirror.

I am pretty sure a dwarf hamster would be too near sighted to see the mirror itself let alone an image.
