No feces is never safe to eat you can never kill all the types of bacteria and germs in there
All???
Cockroaches have been observed feeding on a variety of substances, including decaying matter, food scraps, and even dead insects. While there is limited scientific research on this specific behavior, it is possible that cockroaches may consume sperm if it is present in their environment. However, there is no evidence to suggest that sperm is a significant or preferred food source for cockroaches, and it is unlikely to provide any significant nutritional value to them.
Feces does not eat other feces. Feces is a byproduct of bodily waste and is not able to eat anything. All humans and animals defecate in order to release their waste.
what does the cockroach eat
Yes, cockroaches will eat an onion. The cockroach will feeds on almost anything that is left out on a counter.
Yes, you must let your rabbits eat their own feces because it's an important part of their digestive system. Rabbits need to eat their feces in order to get all the nutrients they need out of their food. If a rabbit is prevented from eating it's feces, it will become ill. (Actually, to be technical, rabbits don't eat their feces at all: they eat their cecotropes, although it looks like they're eating their feces.) See the related questions below for more details.
No rabbits eat their feces, although all rabbits eat cecotropes. Rabbits have two kinds of droppings: feces, and cecotropes. Baby rabbits that aren't weaned yet eat their mother's cecotropes; once they're weaned, they eat their own cecotropes.
Feces or fecal matter is undigested animal waste. All mammals produce feces from the food they eat. Feces is what is left over after the digestive process that the body couldn't use.
Depends what you eat.
Try re-typing your question so I can give you an accurate anwser.
Cockroaches do not make clicking noises when held. However, there are some types of cockroach that makes hissing and stridulating sounds enough to scare a dog or anything that is trying to eat them.
