So I feel really bad because I haven’t been able to let my bunnies out and run around this winter. 

 Lately they have had a behavior change which may be nothing or maybe i should watch more carefully. They lay down a lot …like a lot and they have started to lay down and eat and groom themselves. Just like humans become couch potatoes I’m wondering if this is because they kind of got fat and thus lazy or they are ok. They eat and drink regularly

ADDED DETAILS:

I don’t let them out much this winter. My room has to many danger cords. Usually I let them run in the basement but I am at school full time so its been hard to find time. Once the snow melts i let them run around in their giant pen outside but the snow has to melt first.

I don’t know their age or much history about them  (I rescued them from my  niece who neglected to feed and water them)

An yes I know the cage is small for two rabbits but I have to re- potty train them the cage is higher with shelves so they don’t have to sleep in their litter boxes if they dont want. 

This is lumps and dumps and they look like this a good half of the day lately
