This was a first: This morning, my cat was hunkered down in predator mode, with something on the grass in front of him. So, I had to go see. He had a very fat mouse. I'm guessing she was VERY pregnant. And she was not injured, but was also not moving very much, or very fast because she was laden down with 6 baby mice attached to her. Evidently, they latched onto her so she could move them. They were pretty big. I've never seen the likes of it before. So, since the cat was not completing the job, I scooped the mess up in a bucket, and dumped them in the rooster grow out pen. They gathered around, and had quite the discussion about the matter, but none of them would man up to handle the situation. So, the situation ended with them taking swimming lessons. I hated to do it, but... had I not, the potential population explosion from this litter, plus her next litter would create ongoing issues!
