Ha ha ha..... I KNEW it! KNEW it!
It was only a matter of time.....
You are DOOMED!
I adopted one dog when I worked at the humane society and brought home a puppy to foster and get better and a pregnant cat who delivered kittens under my sofabed--when I was sleeping on the bed. My dog promptly adopted the kittens, my one cat adopted the kittens, and a tug of war between my dog and cat and the mom cat ensued. The dog actually got milk from nursing the kittens. It was hysterical to see the dog sneak to where my cat had left the kittens and steal a kitten and the mom cat to go steal a kitten from the dog. Oy what a zoo!
Spay and neuter is right. Responsible pet ownership--thank you Bob Barker--is the way to go.
