My Cairn terriers weren't feisty at all. I used to be able to take them to see a friend who had 3 dogs and five cats and they would just ignore the cats (initially Rusty went to sniff one and it bopped him on the nose so he ignored tham after that). It would break me out in a cold sweat to even think about taking my Kerry Blue terriers into a house with 5 cats in it!
