Can the Venus flytrap eat meat other than insects?

Absolutely not!

Under no circumstances should a Venus flytrap be fed something that it couldn’t catch on its own in nature.

First of all, this will likely make the trap turn black and die if it actually forms a seal around the meat and starts to digest it. Continually feeding a Venus flytrap stuff like chicken, beef or pork could actually end up killing the plant.

Secondly, it is unlikely that the trap will even seal completely to begin the digestion process because it requires live prey on the inside of the trap struggling to signal the trap to seal.

The only things you should feed your Venus flytraps are insects. Any kind of insect is fine. Flies, beetles, spiders, wasps, earwigs, and pretty much anything that crawls or flies and is an insect is good.

The reality is that you don’t actually need to feed your Venus flytrap anything other than lots of sunlight. If you grow it outside, it will catch all the food it needs on its own and get plenty of sun.
