🦀 We did an event today all about responsible pet ownership!
We took a closer look at some of the most common household pets… and, unfortunately, some of the most commonly misunderstood.
The truth is, many families love their pets deeply but have never been taught what those animals actually need to thrive. It’s rarely intentional. It’s usually a lack of accurate information.
Hermit crabs are one of the best examples of this.
It’s still common to see hermit crabs sold in tiny containers with gravel, a sponge for water, and commercial pellet food. Unfortunately, those setups don’t meet their basic needs and often lead to poor health and shortened lifespans.
Here’s what hermit crabs actually need:
🏖️ Deep sand (and ideally coco fiber mixed in) so they can burrow underground to molt safely.
💧 Both fresh water and marine-grade saltwater pools deep enough to soak in.
🥜 A varied diet including seeds, nuts, vegetables, fruits, proteins, leaf litter, and other natural foods, not just pellets.
🌿 Lots of space to climb, explore, and stay active. In the wild, hermit crabs travel surprising distances, and some keepers even provide exercise wheels!
A few more fun facts:
🫧 Hermit crabs breathe through modified gills, so they need warm temperatures and high humidity to breathe properly.
🐚 Their shells aren’t attached! They’re simply borrowed homes. As hermit crabs grow—or just decide they like a different style—they’ll move into new shells. That’s why they should always have several appropriately sized, natural, unpainted shells to choose from.
👨👩👧 Hermit crabs are social animals and generally do best in groups when they have enough space and resources.
When cared for properly, hermit crabs are fascinating little animals. Watching them climb, forage, explore, and even “shop” for new shells is a reminder that every species has unique needs—and that responsible pet ownership starts with learning.
💚 One of our favorite parts of Critter Caravan is helping people discover how to give animals the lives they deserve. 🦀
