Iguana Brumation Planner

What is the Iguana Brumation Planner?

The Iguana Brumation Planner plans a safe brumation schedule and temperature drop for iguanas. Small, regular health checks and a consistent care schedule catch problems earlier than waiting for obvious symptoms to appear.

Expect roughly 15-20 years with an iguana, which is worth factoring into any long-term plan. As a herbivore, what an iguana needs from its diet changes across its life stages. Green iguanas reach 1.5m and need a custom enclosure the size of a small room, not a vivarium. They are strict herbivores, need intense UVB, and adult males can become genuinely dangerous during breeding season. Health problems that show up most often in iguanas include metabolic bone disease, kidney failure from protein-rich diets, tail and toe loss from poor shedding, which is part of why tracking this over time pays off.

How does the Iguana Brumation Planner work?

Where a schedule is produced, it follows commonly recommended cadences for iguanas; where a score is produced, it uses a simple, transparent scale rather than a black-box formula. The math is only as good as what you feed it, so an accurate, recent input matters more than the formula itself.

What changes the answer

• Age: younger and senior animals typically need more frequent checks than a stable adult
• Existing health conditions: which may call for a tighter schedule than the general default
• Lifestyle factors such as indoor/outdoor access, which affect exposure to parasites and injury
• Your veterinarian's specific recommendations, which should always take priority over a general default

How do you use the Iguana Brumation Planner?

1. Pick the date this was last done
2. Answer "How often do you want to repeat it?"
3. Answer "How many dates to plan ahead?"
4. Answer "How demanding is this animal's routine?"
5. Press Calculate, then read the result alongside the sources listed below

If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this

This calculation assumes a healthy adult iguana with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
