You may find that the pet classifieds offer a mix of good and bad choices. The trick is in discerning between the two. While you’ll find legitimate breeders and individuals with litters of puppies, this can be a costly proposition. You may also be buying a dog who is being bred to exhaustion, just for the money. This isn’t good for the health of the mother or puppies, so you wouldn’t want to buy a puppy in those circumstances. Always inquire, discreetly and politely, about the mother’s age and how many litters she’s had. You can usually get a sense of the general honesty of the seller. On the bright side, kitties are typically free! Among the top choices in the pet classifieds are the pet shelters. Through whatever circumstances, these pets have ended up in an unwanted category.
