#13 Smooth Fox Terrier

Smooth Fox Terriers are great watchdogs, however, they aren’t recommended for households with cats because of their high prey drive.
#14 Standard Schnauzer
Since they have a high prey instinct as well as a fearless nature, they really shouldn’t be cohabitating with any kind of small pet, including cats.
#15 Irish Wolfhound
There’s absolutely no way to anticipate how they might react to having to share their home with a cat.
