Quote - Just because a cat likes eating bread, doesn't mean its good for it.

Even some cats eats some strange things (a strange thing is something that is not meat), the amount that he/she eats is very little.
Dogs love sugar, but their food are not candies, you give some them candy/cake/chocolate only time to time and not every meal.
The extra strange things cause no harm and many times are necessary for some mineral or component that he/she has need in a specific period.
Cats use to eat some plants and grass and then vomit it, they do this for some reason (diuretic, cleaning, medicine ????)

Quote - Dogs are omnivours, like us, however, food thats good for us is not nessesarily good for them.  Dogs have specific dietary needs that are simply NOT met with human cooked meals.

They eat trash and rotten things!!!!, they are the cleaners of Nature!
If you try to eat what dogs love you are dead!

I have a lot of cats, I had some cases where a cat was dying of hunger because he refused to eat artificial food. I saved them giving meat.
In this moment I have three cats with problem, one adult cat that was sick and turned into a skeleton without any force and almost dying and two kitties that beside the milk of their mothers (rotating mother)  there's no way to make them eat. I saved them giving meat, the adult cat now is a nice and healthy cat and so are the kitties, but is a great problem for me they don't eat artificial food!, I have to feed them sepparated from the other cats.

Stupidity also evolves!
