Cats scared of cucumbers!

[Catherine]

They react very strongly. Dogs are a bit of an apex predator. It is the wolf in them. Wolves hunt, they are not usually the hunted.
Smaller cats can be eaten by snakes and birds of prey. 

We were feeding a bearded dragon on Saturday and she suddenly "leaped to safety". She saw the big free roaming iguana at the reptile centre. Iguanas are vegetarian, but bearded dragons are from Australia where there are large predator monitor lizards and birds of prey that could come from above. It was an instinct because this dragon is born in Toronto.
