Recently there has been an incursion of mice in our house. This month alone, our cats have caught four mice (last November: 2, October: 1). The day before yesterday, my sister tells me that sometime in the morning, our tabby-cats (a brother and sister) caught a mouse. Except, the cats had torn the little critter in half. My cat, Blanco, only had the front half in her mouth. The mouse's bottom half was missing, so we assumed, my sister's cat, Bookworm, had it. He didn't and we still can't find it. So, I assuming Bookworm ate the other half.... or stashed it somewheres. My sister thought Domestic Cats weren't Carnivores, so she doesn't like the ideal that they ate a mouse.
