Is it permitted to use the same plates and bowls to feed a pet cat or dog which are also used for eating?

Assuming the pet is fed kosher (for humans) food is this permitted?

Are there any issues with sharing with an animal or their saliva rendering the utensil unkosher?

If so/not, what are the sources of this?

    I'm assuming you don't mean sharing plates without washing them... right? – Daniel Feb 10 '16 at 13:50
  • Can you explain why you think a non-food item (saliva) on a cold dish would render the dish "unkosher?" I can't think of any - dirt isn't treif, it's just dirt. – Isaac Kotlicky Feb 10 '16 at 15:59
  • I don't know if this is something that I would want to do, myself, even after washing the dish. But, consider what the Torah itself, perhaps, implies. How often have our ancestors taken water from a well, lake, or water trough, etc. where animals have drunk from previously? For all we know, they may have drawn water from the well or trough at the same time that the animals were drinking from it! I can't see the case of your dish being any more halachically severe than this. I've seen a few of my (rather weird) friends have their dog lick meat off their dinner plate at the dinner table! – DanF Feb 10 '16 at 16:17
  • I should have added that the plates would be cleaned before we eat off them again and its not something I like to in the first place but in a house with young children and a dog... Well, it can happen. :) – Jakub Feb 10 '16 at 17:53
  • @IsaacKotlicky Good question. I suppose saliva "feels" treyf as the product of a non-kosher animal? – Jakub Feb 10 '16 at 17:55
