What size food should I feed my reptile? This blog is a guide to the best sized frozen rats and mice feeders for Australian reptiles including rats & mice for snakes, lizards, frogs and predatory birds.

What size Frozen Rodents, Rats, Mice & Quail Feeders should I feed my Snake, Lizard and Frog?

During a bushwalk in the Great Dividing Range a few years ago, I came across a mature Coastal Carpet Python that was at the final stages of eating a Wallaby. It seemed almost impossible that this snake with a diameter about the size of a forearm (10cm) had successfully swallowed an animal over twice that. Look online and there are even more extreme examples of large snake food Australia, even snakes eating a cow & another eating a crocodile. Lesson from this that snakes in the wild can eat variable sized prey.

However, in captivity we want our pets to live long & healthy lives so are able to optimise the best rat sizes for snakes, lizards & frogs.

The strongest & simplest guideline amongst herpers is to select food that is slightly larger than the diameter of the thickest part of the snake. This is generally in the middle of the snake. In this way, a snake will have a small lump in its body as it digests, after eating. Refer to the feeder diameters in Table 1 for best rodent size by reptile & animal type.

Other herpers' tips include:

  • Start with the smallest feeder rodent size possible when you first feed a hatchling snake;
  • Increase the size of the feeder rodents regularly as your pet snake ages from pinkie to weaner, small to medium, to large, etc;
  • For hatchlings, start with smaller mice, increase size & as early as possible switch to rats (for some fussy eaters, this can be a challenging stage & there are many techniques to deal with this transition such as rubbing a mouse on a rat before feeding to transfer the smell);
  • Rats are more nutritious than mice over the longer term;
  • Quails are excellent reptile food, creating variety in diet & should be fed occasionally;
  • Feeding smaller feeders more often (say weekly) is considered better for increased growth than an occasional larger feed;
  • If your snake food provided is too big for your snake, they may actually swallow it and then some time later regurgitate it. Not pretty for you or your pet snake!
  • It is often easier to feed one or two feeders per feeding that satisfies their hunger, than trying to feed multiple smaller partial meals in one sitting (which they may refuse after the first few);
  • Weight of snake food ratio: another Herpers guideline is to feed 15 to 20% of a snakes body weight each feed for normal snake growth. To accelerate growth of your snake, feed up to 30 to 35% of your snake’s body weight each feed.

When feeding Bearded Dragon’s frozen mice such as pinkies, Table 5 also indicates the best size of food for lizards, frogs & predatory birds.
