i breed cats and snakes, both are genecically fasinating however the two should not be socialized together. both animals are hunters and cats unlike snakes hunt for pleasure. i have not noticed behaveral difference due to sent or phermones . I keep my snakes in a separate building and the cats live in the house and cattery. over the years the cats have been observed playing with gecko,s skinks unfortunitally reptiles do enter the house and catteries. I have had a cat and tristus fighting ,a bucket of water was used to separate, both animales were ok Also the cats tend to play with snakes , stimies and bredils are been saved from playfull cats CATS SHOULD BE KEPT INSIDE OR IN ENCLOSURES finally still born kittens do make good snake food ,perhaps if cat hatters and people who are scared of snakes took the time to uderstand ,our captive animals THE WORLD WOULD BE A BETTER PLACE I have kept reptiles for 30 years and cats for 14 years
