According to the vet, the exposed skin looks healthy, no flakes to indicate dryness or possible mites. I initially suspected ringworm or mites because during a mites breakout last year & all of the hamsters, except her, were affected. So I thought that maybe it’s her turn to contract mites.

The vet thinks that it’s a psychological issue, mainly that she’s so bored that she overgrooms herself. She can’t groom anymore than the lower back of her body because that’s as far as she can reach.

I don’t understand how she can be bored because she has a lot of things in her cage: a wooden hidey house, a relatively large wheel for her size, plastic & cardboard tubes, ledges to climb on. I’ve since added more stuff in her cage & given her some chewable sticks that I have for the chinchillas & a 42-puzzle playground (that she NEVER goes into even though I hide treats in it!) to the point that there’s little walking space in her bin cage. The vet also suggested that I give her foods that are rich in good oils to encourage fur growth and more toys to keep her entertained. She doesn’t like the plastic ball because it scares her so I’ve only put her in the plastic ball a couple of times when I first got her.

Well, fast forward to today (about 4 weeks later), Pinky has certainly stopped overgrooming herself:

Lesson learned? Pack your hamster’s cage with tons of toys!
