Thanks for the super helpful reply!
I won't mention the frozen rodents having any smell. XD
The hardest part is building confidence. I'm not very confident in asking about things around my dad.
...........I have seven days to prepare. XD He's on vacation right now.
I also have 5 months until his answer becomes important.
And I don't know if I'll still have my rat. That's pretty important.
Thanks for the answers, the more the merrier, but I'll try to get down a list of pros and cons with the snakes and later see what dad thinks.
