When I was a kid we had a cat that had kittens, and my grandmother found a stray mom-cat with kittens in her trailer park that were about the same age and brought her to us to take care of. My mom was mad, but my sister and I were thrilled! Our cat had seven kittens, the stray had four more, so we had 11 kittens! Both mom-cats were black, and they didn't seem to care whose kittens were whose and raised them all together. So cute. All these black and white kittens, except three orange tabbies.
We found homes for all of them, despite my sister & I pleading to keep them all!
