I'm sure you'll still love your pets every bit as much as you did before your wee child entered the picture. Unfortunately, it's not humanly possible to devote as much time to Fido and Fluffy because you're preoccupied caring for an adorable, but very needy infant.
Take a moment to brief your in-laws on the daily feeding schedule your pets enjoy, as well as the location of any pet-related accessories, like the collar, leash, brush and doggie waste bags. If your in-laws are anything like mine, they'll relish the chance to spoil their granddog rotten, although you should stock up on treats. We go through an impressive amount of bones whenever Grandpa or Grannie come to visit, which is probably why they're our pup's favorite people.
