I bet your kitty would rule the roost! When Truman was a puppy, we had a 14 year old male orange tabby and a newly acquired 10 year old female orange tabby...we were a retirement home for orange cats! :D Anyway, I was so worried that he'd be to rambunctious and they'd hide. Well the male did for a bit but our female, who is still with us, gave Truman a few well placed, claw-free, whacks every time he stepped out of line and boy, he learned fast about who was boss.
It was the same with our first bulldog, Bentley. We had a little 8 pound gray tabby who literally backed Bentley up into a corner so he could check out the dog's food bowl.
Bulldogs are so funny. They're big and strong but just like big toddlers! :D
Now my Linus, who was 80 lbs of love, he liked to play with the cats. At first it scared me but I'm not sure I lived until I saw an 80 lbs dog playing with a 6 lb cat.
I'm rambling...many fond memories of our animals together. I've had to pare down since we have two little kids now so we just have one dog and one cat.
