Colossal rats are typically selected by experienced reptile keepers who care for very large snakes, monitors, and other carnivorous exotic pets that require oversized whole prey meals to meet their dietary needs.
Insulated packaging and dry ice are commonly used to help maintain freezing temperatures even during warmer seasons. These shipping materials help reduce temperature fluctuation while the order is moving through transit.
Because of their larger size, Colossal Rats may reduce the need for feeding multiple prey items in one session. Many keepers use them to provide a single substantial meal for larger reptiles.
Sealing, labeling, and organizing frozen feeders simplifies feeding preparation and reduces repeated freezer exposure. Good storage habits also help maintain product freshness and prevent unnecessary waste over time.
After delivery, examine the package for cold temperature retention, frost presence, and overall condition of the product. Feeders that remain frozen or very cold on arrival are typically ready for immediate freezer storage.
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.
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 received my package in the mail today. Thank you for your fast response and quick shipping. The product arrived in excellent condition.
