My baby Colombian grabbed her food butt first.

these animals have been around for millions of years, there's no need to readjust their food for them. the reason they mainly eat head first is because theyre ambush predators and will strike the face as soon as the animal turns to them. they're also opportunistic feeders (feeding on dead/weakened animals) in the wild and will eat whatever comes their way. they have no regards to eating butt first, it all goes in the same.
ive had some of my boas even attempt to eat it sideways, some have even accomplished this! they know what to do, trust their instincts dont work against them.
