Ditto is set to leave on Tuesday. We will miss her. She's been a great companion and we've grown to love her.
Earlier this week I noticed the new hairless hamsters seemed to be a little lethargic, so I set up a space heater near their cage (several feet away pointed in their general direction, set to keep the area just a few degrees warmer than the room). They still looked like they could use a little more help, so I took the seed starting heat mat and put it under their cages. It's conveniently just long enough to go under both side-by-side cages and cover about half the space (so they can also lay on the other side away from the heat mat). The way the ten gallon tanks are set over the edge of the cupboard gives the under-tank heat a natural vent so things don't get too hot under there. Since then the hamsters have been active and seem happy. I've named them Carlos and Sally. Carlos prefers to sleep in the pine shavings, despite having half the tank with fabric cloth. Sally prefers to stash all of her food in her little house on the fabric side and sleep there. Sally loves to run on her wheel, while Carlos only sometimes uses his.
Ditto spends a good portion of every night sitting beside the cages watching the hamsters. I'm sure she'd love to eat them if ever she figured out how to remove the screen lids.
If anyone would be interested in some variegated pothos, or some wandering jew cuttings, or rooted plant starts, let me know. I'd also be happy to barter with them.
