This guide covers frozen/thawed rodent feeders for carnivorous reptiles. For insect-eating species, see the Live Feeder Insects guide.
★★★★★ Ball Pythons — frozen/thawed mice and rats are the standard diet for this species
★★★★★ Corn Snakes — frozen/thawed mice are the standard diet for this species
★★★★★ King Snakes — frozen/thawed mice; size up as the snake grows
★★★★★ Milk Snakes — frozen/thawed mice appropriate to body size
★★★★★ Hognose Snakes — frozen/thawed mice; some individuals require scenting
★★★★☆ Boa Constrictors — frozen/thawed rats; size increases significantly with age
★★★★☆ Blood Pythons — frozen/thawed rats; appropriately sized to body girth
Frozen/Thawed vs. Live Feeding
Frozen/thawed feeders are the standard recommendation for virtually all captive snake keeping. Live rodents can and do injure snakes — bites from live prey are a common cause of injury and infection in captive snakes, particularly when the snake is not actively hunting or is in shed. Frozen/thawed feeders eliminate this risk entirely, are more convenient to store and purchase in bulk, and are widely available from online suppliers.
Most snakes will accept frozen/thawed feeders readily, especially if started on them from a young age. Snakes that have been fed live prey can typically be converted to frozen/thawed with patience and appropriate thawing and presentation technique.
Should I feed frozen or live?
Frozen/thawed is the recommended choice for most keepers. It is safer for the snake (live rodents can and do bite), more convenient, easier to store in bulk, and equally nutritious. There is no nutritional benefit to live feeding. Most experienced keepers and reptile veterinarians recommend frozen/thawed as the default. Live feeding is sometimes used for snakes that persistently refuse frozen prey, but frozen/thawed should always be attempted first.
Feeder Size Guide
| Feeder Size | Approximate Weight | Typical Use |
|---|---|---|
| Pinky Mouse | 2–5g | Hatchling corn snakes, small hognose |
| Fuzzy Mouse | 5–10g | Juvenile corn snakes, small colubrids |
| Hopper Mouse | 10–20g | Sub-adult corn snakes, juvenile ball pythons |
| Adult Mouse | 20–30g | Adult corn snakes, small ball pythons |
| Weaned Rat | 30–60g | Juvenile ball pythons, small boas |
| Small Rat | 60–125g | Sub-adult ball pythons |
| Medium Rat | 125–200g | Adult ball pythons, juvenile boas |
| Large Rat | 200–350g | Large adult ball pythons, adult boas |
A commonly used guideline is to feed a prey item approximately the same diameter as the widest part of the snake’s body. This is a general starting point — individual snakes vary, and some keepers prefer slightly smaller prey items fed more frequently.
Top Suppliers
Most reptile keepers buy frozen feeders directly from specialist suppliers rather than pet stores. Online bulk ordering is significantly more economical and gives access to a full size range. The suppliers below are well-regarded in the reptile community for consistent quality and reliable shipping.
1. RodentPro — Best for Large Orders
One of the largest frozen feeder suppliers in the US reptile hobby. Wide size selection from pinky mice through jumbo rats, competitive bulk pricing, and reliable insulated shipping. A go-to supplier for keepers with multiple snakes or those who want to order in quantity and minimize per-feeder cost.
2. Layne Labs — Best Established Supplier
One of the most established frozen feeder suppliers in the US, with a long track record in the reptile community. Full size range of mice and rats, consistent quality, and available in bulk quantities. A reliable option for keepers who want a well-established supplier with a proven record.
3. Big Cheese Rodents — Best for Ball Python Keepers
A popular frozen feeder supplier well-known in the ball python community. Consistent quality, full rat size range, and competitive pricing. Frequently recommended in ball python forums and communities.
4. Mice Direct — Best for Mice-Only Orders
Specializes in frozen mice across all sizes. A good option for corn snake, king snake, and hognose keepers who primarily need mice rather than rats. Competitive pricing and reliable shipping.
5. Local Pet Store — Best for Occasional Purchases
Most pet stores carry frozen mice and rats in common sizes. More expensive per feeder than online bulk suppliers but convenient for keepers who only need one or two feeders at a time or who need a feeder urgently. Useful as a backup when an online order is delayed.
How to Thaw Frozen Feeders
- Refrigerator thaw (preferred). Move the feeder from the freezer to the refrigerator 24 hours before feeding. Slow thawing in the refrigerator maintains quality and reduces bacterial growth. Bring to room temperature before offering.
- Warm water thaw. Place the frozen feeder in a sealed plastic bag and submerge in warm (not hot) water for 20–30 minutes until fully thawed and warmed through. Check that the feeder is warm to the touch throughout before offering.
- Never microwave. Microwaving frozen feeders causes uneven heating, can create hot spots that burn the snake’s mouth, and degrades feeder quality. Do not use a microwave to thaw feeders.
Presentation Tips
- Use feeding tongs. Always offer frozen/thawed feeders with feeding tongs rather than by hand. This prevents the snake from associating your hand with food and reduces the risk of accidental feeding strikes.
- Warm the feeder. Snakes are heat-sensitive predators. Offering prey warmed to approximate body temperature is generally more effective at triggering a feeding response than offering a room-temperature feeder. After thawing, warm the feeder briefly under a heat lamp or in warm water until it is warm to the touch.
- Wiggle the feeder. Gentle movement with the tongs mimics live prey and can trigger a feeding response in reluctant feeders.
- Feeding location. Most keepers feed inside the enclosure to reduce unnecessary handling before and after meals. Some prefer a separate feeding container for convenience or personal preference. Either approach can work when done properly.
Converting a Live Feeder to Frozen/Thawed
Snakes that have been fed live prey can usually be converted to frozen/thawed with patience. Common techniques include:
- Scenting — rub the frozen/thawed feeder with a live mouse or with bedding from a mouse cage to add live prey scent
- Braining — making a small incision in the skull of the frozen feeder to release scent; effective for stubborn feeders but not necessary for most snakes
- Feeding in a paper bag — placing the snake and feeder in a paper bag creates a confined space that can trigger a feeding response
- Patience — some snakes take several attempts before accepting frozen/thawed; skip a feeding cycle and try again rather than reverting to live prey
Common Mistakes
Feeding Live Prey Routinely
Live rodents can and do injure snakes. Bites from live prey are a common cause of infection and injury in captive snakes. Frozen/thawed feeders are safer for the snake, more convenient, and equally nutritious. There is no nutritional benefit to live feeding.
Offering a Cold or Insufficiently Warmed Feeder
A feeder that is thawed but still cold may reduce the feeding response and is generally less desirable than offering prey warmed to approximate body temperature. Always ensure the feeder is warm throughout before offering.
Feeding Too Large a Prey Item
A prey item that is too large can cause regurgitation, which is stressful and potentially harmful to the snake. Use the body-width guideline as a starting point and size down if the snake regurgitates. If regurgitation occurs, review prey size, enclosure temperatures, and stress factors before feeding again.
Handling the Snake Immediately After Feeding
Allow 48–72 hours after feeding before handling. Handling too soon after a meal can cause regurgitation. This is particularly important for ball pythons, which are prone to regurgitation when stressed post-feeding.
Frequently Asked Questions
Should I feed frozen or live?
Frozen/thawed is the recommended choice for most keepers. It is safer for the snake, more convenient, easier to store in bulk, and equally nutritious. There is no nutritional benefit to live feeding. Most experienced keepers and reptile veterinarians recommend frozen/thawed as the default. Live feeding is sometimes used for snakes that persistently refuse frozen prey, but frozen/thawed should always be attempted first.
How often should I feed my snake?
Feeding frequency varies by species and age. Juvenile snakes generally eat every 5–7 days; adults every 10–14 days. Ball pythons and corn snakes have well-documented feeding schedules — follow species-specific guides for precise recommendations.
My snake won’t eat. What should I do?
Feeding refusals are common in snakes and are not always a cause for concern. Common causes include: being in shed, seasonal changes (particularly in autumn for ball pythons), stress from a new enclosure, incorrect temperatures, or individual preference. Review husbandry before assuming a health issue. If the snake has not eaten for more than 6–8 weeks and is losing visible body condition, consult a reptile veterinarian.
Can I refreeze a thawed feeder?
No — do not refreeze a thawed feeder. Refreezing degrades quality and increases bacterial load. If a thawed feeder is not accepted, discard it and try again at the next feeding.
How do I store frozen feeders?
Store in a dedicated freezer or a clearly labeled section of your household freezer. Keep in sealed bags to prevent freezer burn and odor transfer. Properly stored frozen feeders maintain quality for 6–12 months.
