M: Sometimes when she’s in a blanket or sitting on my shirt, my hedgehog will start scratching at the cloth. Do you have any idea what she might be trying to do? Because it doesn’t seem like she’s trying to get comfortable.

G: It could be a few things:

  1. Scent Marking / Investigating – Hedgehogs have a strong sense of smell, and she might be reacting to a scent on the fabric. Scratching could be part of her exploring or trying to get more information.
  2. Anointing Behavior – If she licks or foams at the mouth afterward, she might be trying to gather the scent for self-anointing. Even if she doesn’t, some hedgehogs react to certain textures or scents with excited scratching.
  3. Burrowing Instinct – Even if she’s not actively nestling in, she might be trying to manipulate the fabric into a more familiar or enclosed space.
  4. Frustration or Discomfort – If she seems restless, she might not like the texture or temperature of the fabric.

Does she do this with all fabrics or just specific ones?

M: We have to keep changing blankets because she’s having health issues and keeps soiling them… the one time she definitely seems to is if she’s crawling around on my chest and reaches the area around my arm. It doesn’t seem to matter if it’s a fresh shirt or well worn

G: If it's happening specifically near your arm, she might be reacting to your natural scent, body heat, or even the way the fabric folds in that area. Some hedgehogs get fixated on certain spots due to scent association, and if she has any vision issues (which can happen with age or health problems), she might be using scratching as a way to "map out" the area.

Given her health issues, discomfort or mild agitation could also be a factor. If she’s dealing with any skin irritation, pain, or internal issues, the scratching might be more of a stress response rather than an attempt to interact with the fabric. Have you noticed any other changes in her behavior?

M: This isn’t a change. It’s an ongoing thing – the only reason I mentioned it is because one of the possibilities was either a positive or negative reaction to different fabrics, and that introduction of new materials could likely complicate analysis. I have a feeling there’s room for all of your possibilities – now that I know major options, I can look for more and better clues

G: That makes sense. If it’s ongoing and not tied to fabric changes, then scent, instinctual behavior, or a personal quirk are probably the bigger factors. Since you know her well, you’ll probably start noticing patterns now that you have a few possibilities in mind. Let me know if you pick up on anything new—I’m curious what you figure out.
