Question...

I have 2 ball pythons - neither one is an aggressive eater. So today is feeding day and I set everything up to pre-scent the tank. Hoping this will make the feeding process go smoother. We can all dream right? Anyway, how long should I do this for? And... should I pre-scent both tanks? Meaning the one they live in and the one they will be fed in? I'm sure that question sounds so stupid - I just want to get it right. I try to keep everything in their tanks perfect, I can be a little OCD about the snakes.

Thanks in advance for any help you can offer!
