Lady Rat (of the large operation, and then unrelated facial abscess; her name is actually Dean) is currently in the single-level hospital cage. This is because she has a large open wound on her face. I'd like her to go back in the main cage, but separation at the moment makes it easier to feed her high-calorie food without the youngsters coming along to steal it

Also, it makes it less likely anything will get in to the large open wound. Plus, it gives me time to re-arrange the main cage, since her back legs are starting to weaken - she has no problem climbing up things, but isn't so good at getting down. So ladders, etc, are being replaced with gently sloping hammocks to provide soft slide-down-able transportation.
Anyway, the hospital cage, for all its yummy food, is rather boring. Today I popped one of the youngsters in there with her. Youngster (whose name is actualy Lovell) was not initially impressed - why am i shoved in the boring single-level cage? What's going on? She located some yummy food though (not much of it!), and all looked OK. I have been down to lunch, and I see they are curled up together in the house, having a good snooze.
This is great

Dean has definitely been really enjoying my company the last few days - she is bored on her own. So this way she gets some rat-company and social things like grooming which I can't provide(!), but will still have the advantages of being on her own at mealtimes. Once I get the cage 'converted', then she should be able to go back in the main cage, and just come out for mealtimes. She's old-approaching-ancient, but she sure as heck isn't giving up
