Yes Reh-Hen we've had ratties for yrs. they know which animals belong to us & which are not, that extends to your rabbits which if they find a baby (kit) they will gently pick it up & take it to the garage & try to nurse it, we have been having problem with the eggs, a new pup got thtem into stealing but when we caught them in the act they, your not going to belive this, but they bring the eggs they find to the door, is a bird gets out they have a different bark to let us know something is not right. But we have the oldest line in So. Ca. my dadstarted breeding this line 20yr ago. so we have had alot of gen to work with. I have some pics of ducks, chickens, dogs & turtle all eating toghter if I can find I figure out how to post it.
But just work with them & let them know what you expect of them & be consistent about it
