So i recently got a ball python and im having trouble feeding/ need advice.
I do have another snake that isnt a ball python and have never had trouble feeding it.
So my ball python was trying to eat it as you can see but managed to get loads of substrate on the mouse. Does anyone have any tips on how to avoid this?? And no i did not let her eat this mouse im hoping to try again tomorrow. She currently has substrate in her mouth and im not sure how to get it out/ if its gonna affect her badly? If anyone has any tips or what i can do please comment

What are these on my dogs chin??? Not sure if i should be worried or not

Im 16F and i feel so ugly. How can i look better?
