Vet Darren Partridge Shares Spring Changes for Exotic Pets
March 18, 2026
As spring arrives, the longer days don’t just affect us, they also trigger important biological changes in exotic pets such as reptiles and amphibians. Light levels play a key role in regulating hormones, appetite, activity and shedding, which is why this season is an ideal time to review your pet’s setup.
In this article, Molesey Vets’ exotics enthusiast and Vet Darren Partridge shares the key things you need to check in your pet’s enclosure as the new season starts.

Spring changes in exotic pets: lighting, heating and shedding
Why light matters
Many exotic species rely on changes in daylight to signal seasonal shifts in behaviour. As natural light increases, you may notice your pet becoming more active, eating differently or preparing to shed. Darren explains that artificial lighting should support these changes rather than conflict with them, which is why ensuring your equipment is working as it should is so important.
UV lighting: strength fades over time
UV bulbs are essential for species such as tortoises, lizards and some snakes, helping them process calcium and maintain healthy bones. However, even when a bulb still appears bright, its UV output can drop significantly over time. Darren shares that most UV bulbs need replacing every 6–12 months, depending on the type. Spring is a sensible moment to check dates and upgrade if needed.
Heating and temperature gradients
As outdoor temperatures rise in Surrey, indoor enclosures can heat up more quickly than expected. It’s important to check thermostats, basking spots and overnight temperatures to ensure your pet still has a safe temperature gradient. Small adjustments can prevent overheating and support healthy digestion and activity levels.
Shedding and skin health
Seasonal changes often coincide with increased shedding. Proper humidity, lighting and nutrition all play a part in making sheds smooth and complete for your pet. Incomplete shedding or retained skin can signal that something in the environment needs adjusting.
A good time for a refresh
Darren suggests that spring is ideal for a full equipment review — checking bulbs, heat sources, timers and thermostats and making sure everything is clean, safe and correctly positioned. These small changes can have a big impact on your pet’s comfort and long-term health.
