Chlorinated Water

Some people have concerns with chlorine in tap water, but there have been no reported problems with crested geckos. Certain other reptiles may be more sensitive – and amphibians and fish are definitely sensitive to tap water. If your tap water is safe (you can check quality reports online for most municipal areas), then there’s no real problem with using plain old tap water. However, if you live in an area with contaminated tap or well water, or if you have a variety of animals like fish and amphibians to care for, you should learn about chlorinated water and how to deal with it.

How is Chlorinated Water Harmful?

For most animals, chlorinated water is not a concern. Humans may find the taste unpleasant, and the water can still contain sediments and dissolved solids that could cause other issues of water quality. Always use water sources approved for human use. For example some outdoor pipes, spigots and garden hoses are not labeled for drinking water. They can impart lead and other harmful elements to an otherwise safe water source!

One concern for reptile keepers with glass or clear plastic enclosures is that the minerals in tap water cause hard water deposits. This impairs viewing and can interfere with adhesion of arboreal geckos, like cresteds.

Chlorine and chloramine are chemicals used to treat tap water to make it safe for human consumption; it is assumed that it is therefor safe for other non-aquatic vertebrates. Animals that don’t live in water ingest water orally, and the chemicals are broken down while it works its way through the digestive system, before reaching the bloodstream. These chemicals are used because they kill microorganisms that can make you – and possibly your pets – sick.

Drinking water

Chlorine and chloramine, a combination of chlorine and ammonia, are highly toxic to fish because it causes gill necrosis. Chlorine and chloramine may do the same thing to lungs if they were constantly exposed the way fish gills are to water containing the treatment. However, it’s just the nature of the aquatic environment and the way gills work. Similarly, amphibians like frogs, toads and salamanders have semi-permeable skin that lets a variety of chemicals access the bloodstream directly. The only direct harm to reptiles would be if they routinely soak in water and take in the chemicals via the cloaca, which may then enter the bloodstream without being digested.

So if you have chlorinated water, and don’t want to use it – what can you do about it? You can dechlorinate your water or you can use a different source. To make water safe for fish or amphibians, you need to either remove the contaminants from tap water or use a different source of water.

Menadione Synthetic Vitamin K

Menadione sodium bisulfite complex (synthetic vitamin K) is a common supplement in pet food. With the trend moving towards more natural, holistic and organic pet foods, this additive has become a controversial ingredient because of a misunderstanding of its purpose and its toxic effects in certain laboratory settings.

Menadione Safety Concerns?

It’s true that menadione has some cytotoxic effects, depending on its purity and dose. It is also being studied for its anti-cancer and anti-inflammatory benefits. Some concern comes from the fact that the product has a Material Safety Data Sheet that outlines some concerns and cautionary procedures when working with the substance. However, many common products have MSDS labeling. One reason there is a MSDS for menadione is because it’s typically handled in a setting where it is mixed to form other products; since there are some concerns, it gets reported on the sheet. The same is true for many ingredients of common products, like Vitamin C. It sounds scary when named ascorbic acid and has its own MSDS: “MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic for
bacteria and/or yeast.” Whoa!

Check out calcium carbonate’s MSDS: “The substance may be toxic to kidneys. Repeated or prolonged exposure to the substance can produce target organs damage.” However, this really boils down to handle any purified substance with care; don’t inhale any powders; and too much of anything is bad for you.

In case the Group 3 Carcinagenic in the MSDS for menadione scares you, it’s simply the group for substances unclassifiable to carcinogenicity in humans. The following list the categories of possible carcinogens according to International Agency for Research on Cancer:

Group 1: Carcinogenic to humans
Group 2A: Probably carcinogenic to humans
Group 2B: Possibly carcinogenic to humans
Group 3: Unclassifiable as to carcinogenicity in humans
Group 4: Probably not carcinogenic to humans

To be clear, this is not proof that it is not carcinogenic, just that it has not been proven in humans. The data on causing cancer in animal cells is also a little muddied. It is understandable to be careful with it. However, it appears that eating grilled meat and potato chips is more likely to be cancer-causing.

Menadione in Pet Food

As for the use of MSBC in animal feed, it’s been around for a long, long time and there are no verified, well-cited studies that I can find that indicate it has ever caused harm when used in small doses as a food additive. I have emphasized the last part because injections of large-doses of synthetic Vitamin K can lead to issues; again, too much of anything is harmful. “The dose makes the Poison” – Paracelsus.

There are numerous claims from well-meaning, but misguided, bloggers, animal caretakers and those that fall for the “Appeal to Nature” fallacy. The way we arbitrarily classify products as “natural” or “artificial” is inherently flawed and we cannot let something as important as health be swayed by personal philosophy.

This is where an understanding of the scientific comes in very handy. Just wanting something to be true does not make it true. The more people you convince that something is true does not make it true. Anecdotal evidence can only be trusted so far. Actual research and experimentation should be the basis of any health, nutrition or science claim.

Polydactyl Crested Geckos

Polydactyly (or polydactylism) is a scientific term for having extra digits (fingers or toes) beyond the number than is considered normal for the majority of the population. Extra toes are not always present in the same number on both feet or among individuals; this irregularity has caused some concern about the genetic fitness of this trait and its impact within a population. Polydactyly has been found in mammals (including humans), birds and reptiles. Few examples are found in the wild, but they do occur[1].

RC-1d

Some people view any structural difference as a “flaw” and therefor undesirable. Show standards are influenced by what people expect to see in an animal. Enthusiasts don’t want to reproduce such a disqualifying flaw in their breeding stock. We aren’t there yet with crested geckos or any other reptiles. However, most of us strive to breed for the nicest-looking geckos and to some, and an extra toe is just plain weird.

There is a lot of misunderstanding around these extra toes. Some see anything like this as a suspicious product of inbreeding. Through a bit of research, we believe that the forms of polydactyly seen in crested geckos are really just a random mutation that, while heritable, is not a reflection of inbreeding. Keepers are breeding thousands of these geckos a year, and mutations are bound to appear more often. That doesn’t necessarily mean that the rate of occurrence is changing. However, because there is a strong genetic link that is heritable, we do understand the caution many breeders feel regarding this trait.
