Pinkies? Your writing style suggests a knowledge of (many) things pets, very humorous situations, and unsavory characters- who shouldn't really be hanging around animals. I remember my pets (I still have them, four cats and a dog.) Readers who own these little fuzzballs or scaly ones know your pain. Feeding them is such a hassle! I myself am a male, but I totally saw where the poor mother's fear came from.
So if you put "horror" as a genre it would work. Baby mice, much less frozen? Some Jesus lizard... Ha-ha-ha, I'm kidding. But seriously, five stars for a highly enjoyable story!
Now, you can read the story yourself. It is funny and highly realistic. Oh and if you are a member of PETA it might not be your thing. http://www.writing.com/main/view_item/item_id/1830538-The-Jesus-Lizard
