All right, another pet related post. I can't help it.
Can I point out how wonderful mother dogs and cats are? They can have just finished nursing a large litter of their own (we're talking 6-9 babies in some cases) and are sore and thin and tired and deserving of rest, and despite this, will accept another large litter of orphans as their own. I know that there are women out there who have done this over the ages, but really, puppy and kitten teeth are sharp!
