Crabs eating cheese: safe or not?
There are conflicting opinions on whether crabs can safely eat cheese. Some sources claim that it is safe for crabs to consume cheese, while others argue that it is an unnatural food for them and may not provide any nutritional benefits.
Those who support the idea of crabs eating cheese argue that it is safe and that they enjoy it. They may even crave the variety in their diet. One source mentions that their hermit crabs enjoyed eating small chunks of birthday cake, which contained cheese, and did not exhibit any negative behavior or health issues afterward. Another source mentions that their hermit crabs have been consuming dairy for many years without any issues.
On the other hand, some people are concerned about the potential lack of digestive enzymes in crabs that would allow them to properly digest dairy products. Crabs, like other non-mammals, may not have the enzyme lactase, which is necessary to break down lactose, a sugar found in milk and dairy products. Without lactase, crabs may not be able to derive any nutritional benefit from consuming cheese.
Additionally, some people find the idea of feeding cheese to crabs unappealing, as it is not a natural part of their diet in the wild. They argue that even if cheese does not harm the crabs, it may fill them up without providing any nutritional value.
While there may be anecdotal evidence that crabs can safely consume cheese, more scientific research is needed to definitively determine its safety and nutritional impact on these crustaceans. In the meantime, it is up to each crab owner to decide whether or not to include cheese in their crab's diet, weighing the potential risks and benefits.

Crabs eating cheese: nutritious or not?
There are conflicting opinions on whether crabs can safely eat cheese. Some sources claim that hermit crabs do eat cheese and that it is safe for them to do so, while others argue that it is an unnatural food for crabs and may not provide them with any nutritional benefits.
Those who support the idea of crabs consuming cheese argue that it is safe and that they enjoy it. They may even get it about once a month as a treat. Some people have fed their crabs small amounts of cheese without observing any negative effects, debunking the myth that cheese is lethal to crabs.
On the other hand, some people are concerned about the lack of scientific evidence supporting the practice. Crabs, like other non-mammals, do not produce the enzyme lactase, which is necessary to break down lactose, a sugar found in dairy products. Without lactase, crabs may be unable to digest lactose properly, raising questions about the nutritional value of cheese for crabs.
Additionally, some people find the idea of feeding cheese to crabs unappealing, as it is not a natural part of their diet in the wild. They argue that crabs should be fed a variety of foods, including fruits and hermit crab food, which are more suitable and nutritious options.
It is worth noting that the opinions on this topic are mostly based on personal experiences and anecdotes rather than scientific research. While some people have observed their crabs enjoying cheese without harm, there is still a lack of conclusive evidence to support the widespread recommendation of cheese as a safe and nutritious food for crabs.

Crabs eating cheese: myths and facts
Crabs eating cheese has been a topic of discussion for many crab owners and enthusiasts. While some people believe that cheese is a safe and enjoyable treat for crabs, others argue that it is unnatural and may not provide any nutritional benefits. So, what is the truth? Can crabs safely eat cheese?
Let's start by addressing the myths and misconceptions. One common myth is that crabs cannot digest dairy products because they lack the enzyme lactase, which is necessary to break down lactose. However, this claim has been questioned by crab owners who have observed their pets eating cheese without any negative consequences. In fact, some crabs seem to enjoy cheese as a treat and have been known to crawl up wood walls to get to it. Additionally, it is worth noting that casein, a milk protein, is reportedly 96% digestible by farmed crustaceans, further debunking the myth that crabs cannot digest dairy.
Another misconception is that cheese is an unnatural food for crabs and therefore should not be fed to them. While it is true that cheese is not typically found in a crab's native environment, this does not necessarily mean it is unhealthy or unsafe. Crabs are known to eat a variety of foods that are not naturally occurring in their environment, such as hemp seed, rooibos, and roses, with great results.
Now, let's explore the facts. It is important to note that there is limited scientific research specifically on whether crabs can safely eat cheese. However, some crab owners and experts have conducted their own experiments and shared their findings. One notable example is Julia Crab (aka Kerie), a member of the Crustacean Society, who reportedly fed her crabs small chunks of birthday cake, including cheese, with no ill effects. This observation challenges the notion that dairy is lethal to crabs.
Additionally, it is worth mentioning that the Hermit Crab Association (HCA) Safe Food list, last updated in 2015, notes that food trials for dairy are still ongoing. While some people interpret this as a sign of potential danger, others argue that it simply indicates a lack of conclusive evidence. The HCA list also mentions that some dairy products, like yogurt and cottage cheese with live cultures, may be beneficial for crabs as they can create some lactase, aiding in digestion.
In conclusion, while there may be misconceptions and uncertainties surrounding crabs and cheese, the available evidence suggests that cheese can be safely offered to crabs in moderation as a treat. However, it is important to use organically produced dairy products to avoid any potential harm from antibiotics and growth hormones. As with any pet, a varied diet with a balance of nutritious foods is essential for the well-being of crabs.

Crabs eating cheese: scientific evidence
There is much debate among crab enthusiasts about whether or not crabs can eat cheese. Some people believe that cheese is harmful to crabs, while others claim that it is safe for them to consume. Those in favour of crabs eating cheese have pointed out that crabs will eat all sorts of food in the wild, including trash, dog food, and other pet foods. They also note that crabs have a great sense of smell and will crawl up wood walls to get to food stored out of reach.
There is also some scientific evidence to support the idea that crabs can eat cheese. For example, one source mentions that casein, a milk protein, is 96% digestible by farmed crustaceans. Additionally, the live cultures in some yogurts and cottage cheeses can create some lactase, which is necessary for breaking down lactose, even though it is unclear if this would be enough for a lactase-deficient crustacean.
However, there are also concerns about the potential harm of feeding dairy to crabs. Crabs, like other non-mammals, do not produce the enzyme lactase, which is necessary for digesting lactose. As a result, they may not be able to derive any nutritional benefit from consuming dairy products. Some people also find the idea of feeding cheese to crabs unappealing, as it is an unnatural food source for them.
Despite the ongoing debate, some crab owners have reported feeding their crabs small amounts of cheese without any negative consequences. One person even reported that their crabs "absolutely dived into" the cheese. Nevertheless, it is important to approach this topic with caution and consult with a crustacean expert before feeding dairy to crabs.

Crabs eating cheese: opinions and beliefs
There are mixed opinions and beliefs about whether crabs can eat cheese. While some people believe that cheese is safe for crabs to consume, others argue that it is an unnatural food for them and may not provide any nutritional benefits.
Some crab owners have reported that their crabs enjoy eating cheese and have not suffered any ill effects. For example, Kerie (aka Julia Crab), a member of the Crustacean Society, wrote about feeding her hermit crabs small chunks of cake and cheese, which they eagerly ate without any negative consequences. She also mentioned that she had not found any scientific evidence to support the claim that dairy products are lethal to crabs. Another crab owner, Niko, shared a similar experience, stating that their land hermit crabs (LHC) have been consuming dairy for years without any issues. Niko also noted that crabs in captivity often eat a variety of foods that are not found in their natural environment, such as trash, dog food, and pet food.
On the other hand, some people are hesitant to feed cheese to crabs due to concerns about dairy digestion. Crabs, like other non-mammals, lack the enzyme lactase, which is necessary for breaking down lactose, the sugar found in milk and dairy products. Without lactase, crabs may not be able to digest and benefit from the nutrients in cheese. However, it is important to note that the live cultures in some yogurts and cottage cheeses can create lactase, although it is unclear if this would be sufficient for crabs.
The Hermit Crab Association (HCA) has also weighed in on the topic, noting that cheese is not a natural food for crabs and that some people may be uncomfortable offering it to their pets. The HCA Safe Food list, last updated in 2015, mentions that food trials for dairy are ongoing, indicating that the safety of dairy for crabs is still being evaluated. While some crab owners are open to trying dairy products, others prefer to stick to more traditional foods like fruits and hermit crab food pellets.
Overall, the opinions and beliefs about crabs eating cheese vary. While some crab owners have successfully incorporated cheese into their pet's diet, others remain cautious due to the potential digestive challenges associated with dairy consumption in non-mammals. It is essential to conduct thorough research and consult with experts before feeding cheese to crabs to ensure their health and well-being.
