A snake fed a meal that's too big for it will often refuse to eat at all, and getting that size judgement wrong is one of the most common feeding mistakes new reptile keepers make. Sizing by weight band rather than guesswork is how EvoRx get round it.

Each feeding parcel is weighed to a standardised specification rather than approximate sizing, which the manufacturer says helps eliminate guesswork. The range runs from pinkie through to jumbo, letting keepers match the size precisely to the animal being fed, and every batch is described as undergoing microbiological screening.

• Standardised, weighed feeding parcels — not approximate sizing
• Available across sizes from pinkie to jumbo
• 6 parcels per pack
• Complete food, formulated for snakes and other carnivorous or omnivorous reptiles
• Every batch screened for pathogens and bacteria, per EvoRx

What the makers don't tell us. Beyond the weight-band naming, there's no specific gram figure or nutritional percentage supplied on this card, so matching a size to your snake still relies on the size name (pinkie, small, large and so on) rather than an exact weight we can quote you.

Who it's for: snake keepers who want a frozen feeding programme sized consistently rather than variable-weight prey — check which named size matches your animal's current feeding requirement before ordering.
