I have never seen this happen before I was feeding my ballpython a small frozen rat, and she went up to it and gently put her mouth on it and did not constrict it. She just knawd on it for a minute then let it go and went back in the hide. This would be the I’ve only fed her the rats 2 times before this incendent, and this certain rat is one of the bigger ones of the four I purchased. Should I just try again later or is she not hungry can someone give me an explanation. Also I have never had trouble feeding her before.
