Choose a feeder that closely matches the widest part of your snake’s body. Small adult mice are commonly suitable for medium-sized snakes transitioning from hoppers.
Yes, but only if your reptile consistently handles hopper mice without digestion issues. Gradually increasing prey size helps reduce feeding stress and the risk of regurgitation.
Yes. Small adult mice contain more developed muscle, bone, and fat content, making them better suited for growing or mature reptiles.
Small adult mice weigh significantly more per piece, so lower package counts still provide a substantial total feeder weight.
Yes. A standard freezer works well for long-term storage, provided the feeders remain consistently frozen after delivery.
Orders are packed with insulation and dry ice to help maintain frozen temperatures throughout normal FedEx Ground transit times.
I’ve been in the reptile hobby for over 15 years, and consistency is everything. Big Cheese has never let me down. Every order shows up exactly how it should—clean, properly packaged, and ready to go. That kind of reliability is rare these days.
After FedEx lost my first shipment... I received the replacement shipment yesterday! My snakes ate this morning :-).I have never ordered from The Big Cheese Rodent Factory before. I have gotten rats from expos and other online retailers. I used AI to hunt through options and landed with you. A few points... First, with the FedEx problem. I could not have dreamed of a better response from your company. I appreciate how quickly you shipped out the replacement rats! Second, your rats are the cleanest rats I have ever seen, and packaged extremely well!. My snakes are great eaters (2 adult ball pythons a juvenile boa and an adult boa) . All of the snakes ate immediately when the rats were offered.I want to thank and praise you for this entire experience. If you have a list of places that are more influential for me to leave a positive review please let me know.I will 100% order from you again (and again, and again) Thanks!
This was the first time I have ordered from your company as well as ordering frozen mice/rats through the mail. I am so impressed with the shipment, packing, and the way the mice/rats are packaged. I have not opened them yet, but they appear to be very fresh. The Go Herping channel on Youtube highly recommended your company. I look forward to trying out your products on my milk snake and ball python. With the way you took such care in the packing of the rodents, as well as the packing/shipping, I am quite sure I will be very pleased. Thank you so much and have a wonderful afternoon.
I placed my order and received my order in perfect condition. Thanks for your help, looking forward to doing more business with you in the future.
Hi, just wanted to say that our rodents arrived today. Wednesday the 21st. You guys have outstanding rodents. After buying from a petshop the last few years, I’ve seen the light. There is o comparison. My snakes ate like they’d never had a meal before, LOL
We received the mice last week and are very happy with them. Thanks a lot for making this so easy, and I’ll be happy to give you my business when we need feeders in the future.
I just had to stop in the middle of a feeding session to thank you. Just as food and water are the staples of human life, of course rodents are the sole foundation of my career. I have been impressed lately with the quality of your rodents. Not just lately, but all along. It just […]
