We are not alone

Morty and Eli are not the first cats to live in this apartment. Today, we discovered signs of the previous cat(s)'s presence.

The kitties have been without their toy mice for a couple weeks now since they were swatted under the stove within a two-hour time period. While using the back end of a fly swatter to retrieve the lost mice, I found four of the sock mice I've bought for Morty and Eli (because those mice are cuter than the weird furry ones) and one dark blue mouse of unknown origins. At that moment, I remembered that my neighbor mentioned that the previous tenant's cat(s) used to watch him through the window like Morty and Eli do.

Needless to say, I tossed the old mouse, which was manky beyond describing.
