Can confirm. I think it was someone on this forum (or maybe somewhere else) awhile ago whose boa constrictor ate its entire repti-carpet, just because it had some leftover scent of rat on it. LOL. It regurgitated it later.
Different snakes have different methods of examining "what is food" too. Green Tree Pythons mainly track heat and movement, less than scent. Anything that's warm and moves at night is possible food in their book. Ball pythons seem to rely heavily on scent and then heat.
Anyway, kind of off-track from the topic...
