Having brought a puppy into the house while owning a cat, and having
brought a kitten into the house while having a dog, I would recommend you
wait until your little loved ones have adjusted to the new home! I have
moved several times with pets, and while they always (almost always)
adapt, it is still one of the most stressful things that can happen in
their little lives. With a child you can explain, with a pet, you just
have to give lots of extra love!
