Introducing a Kitten To An Older Cat or Dog | Eukanuba

Kittens and older pets

Even if your older dog or cat has lived peacefully with other animals in the house, there is no guarantee that a new kitten will be welcomed with joy, or even tolerance!

Some benign older animals will readily accept any pet brought into the home. Usually, however, even the calmest dog or cat will be concerned at the appearance of a new kitten.
