When I was out looking for a tub I saw the little 2.7qt tubs and the next size up was 12. So I ended up with the 12. I was thinking the 2.7 would be too small so I got the 12. Should I go back out and look for a 6 somewhere else, or do you think the 12qt is worth a shot. I gave her about 3in of aspen to burrow in. I got the temp up to around 80F.
