Is my hamster acting normal after anesthetic at the vets?

My hamster tiger-lily is 2 and had to have anesthetic to get her teeth done as they had gotten too long and they couldn t keep her still for it. She pulled through it fine. We ve got her home, but it s been 9 hours and she keeps falling asleep in the tubes, which is really not normal for her. She normally sleeps in her box. but she keeps falling asleep in her tubes. I can wake her and she come out and have a drink, but she goes straight back in there.

Is this behavior normal?

The only explanation I can think is that mum put the box she normally sleeps in, in the transport cage we have for her, and she was taken to the vets in it, and I m thinking she doesn t want to go back in because it brings back bad memories, makes her scared

Thanks,

Zoe
