Here is a detailed response to Christians, including Sam Shamoun, on the scientific error in the Bible about rabbits chewing the cud:
https://quranandbibleblog.wordpress.com/2018/12/07/on-rabbits-and-rumination-a-response-to-christian-interpretations-of-leviticus-115-6/Some excerpts:
"The problem is that the verses claim that both hyraxes and rabbits “chew the cud”. In other words, they regurgitate partially digested food to chew it again and then swallow it. This is done in order to gain the most nutrients from the food. This complex process is called “rumination”.[3] Animals such as cows, sheep and goats are categorized as “ruminants”.[4] But animals like hyraxes and rabbits are not ruminants because they do not regurgitate their food in order to chew it again. Rather, they are categorized as “non-ruminant herbivores”.[5] Thus, skeptics of the Bible claim that Leviticus 11:5-6 is a scientific error and clear evidence to disprove the Bible’s alleged “inerrancy”."
"Perhaps Shamoun should pick up a science book once in a while, because this is an inaccurate claim. While rabbits do perform the process called “refection”, also known as “caecotrophy”, in which they swallow soft feces, they do not “chew” it. Rather, the pellet of feces is swallowed whole. As stated in the book “Nutrition of the Rabbit”:
“[h]ard pellets are voided, but soft pellets are recovered by the rabbit directly upon being expelled from the anus. To do this the rabbit twists itself around, sucks in the soft faeces as they emerge from the anus and then swallows without chewing them.”[7]"
