Whenever I defrost a mouse for Cassie, I put it on a square of paper towel under the heat lamp until it reaches around 30-35 degrees (making sure it’s thoroughly defrosted inside and out first). On a few occasions, I took her out of her click clack and let her find and take the mouse by herself. Today is her feeding day, but she’s due to shed in next day or two, so I’m postponing the feed. She’s been sitting on her perch since last Sunday (when she went milky-eyed) pretty much not moving. Today I booked her in for a visit with a reptile vet for a general health check-up and hopefully sexing (so as of next week, Cassandra might become Castiel, lol). They suggested that if possible, I should collect a stool sample before the visit. I thought that the best way to collect it is to put a piece of tissue under her pooping spot, as it would be easier to see and won’t get covered in substrate. (In theory, at least) She was not bothered at all by me doing it, however, a few minutes after I put it in there, she became very excited and started investigating the tissue - most activity she has done in a week. I was wondering if she’s curious about the new addition, but she has never acted like that around anything else I put in her click clack. I assume that she has learned to associate white paper towel/tissue = food, even though she was fed off the paper towel only a few times, and even though this tissue didn’t smell like a mouse. I have also placed a wetted, *scrunched* paper towel in her click clack last time she was shedding to elevate humidity in her click clack, and another one since Sunday, but she showed no interest. Has anyone else observed learning behaviour in their snakes? Especially if not food-related?
