I'm sure that after a geneticist from the Passo Fundo University did take the blood we will never hear anything about it again ('cause it's just blahblah)
Haha, It reminds me of a book by R.L stine/goosebumps (I sort of forget) about dogs breeding with cats becoming a horrendous monster. It had a little story about how dogs and cats around the farm sometimes -- but rarely bred, if they did farmers would have to kill them because they were ugly and very aggressive. Of course that's just a silly horror flick story as for it actually happening that'd be fairly interesting...
Humoring the story to assume -if- a cat and dog did breed it would have to be a toy/small dog. Also the skull shape looks like some sort of pitbull breed to me.
Edit- what I'm trying to say is - when animals are born they share visual similarties with other animals. Lets say you have a baby and it's nose is sort of pointed up a tiny bit that 'resembles' a pig, but this doesn't mean you shagged with one does it :P?
