Cats and Fish.
I know, dull.
Chloe, our female calico. About 2 years old.
Prowl, our black and white male longhair. Got him as a feral stray when he was a kitten. 4 years old.
Both curled up together, after Chloe came home after spaying. They liked my bookbag!
I also have a community aquarium, with tinfoil barbs, swordtails, hatchetfish, cories, a pleco, some danios and rasboras and black tetras. I'm rather fond of the tiger barbs, and have raised them since they were an inch long -- they'll need a new tank soon, and are a perfect reason for me to get that 75 gallon tank I've been dreaming of...
I normally wouldn't bother, but the barbs are trained to respond to light tapping on the tank to DANCE DANCE revolution for their food.
