but also that there would be more fur-covered surface area and maybe even an overall increase in nondigestible caca?
I was thinking the same thing.....but what Seamus said kinda answers this question....since the smaller prey items have a smaller surface area, the "good stuf" inside will be digested quicker and more easily....neutralizing the greater amount of undigestable hair, etc.

I have a male Western Hognose snake who eats anywhere from every 2-7 days depending on what leftovers I have and when he is shedding...he has shown an amazing rate of growth, much moreso than some of my other colubrids. This is a very interesting topic indeed.

That's why the first post had the line about different prey items... A prey item with less hair, no hair, thinner hair or the like would clearly change the rate of digestion, similarly the mass of indigestable tissue as it is a percentage of the whole will play a role... Mice as a general rule tend to be a bit less meaty than a rat to begin with but breeder mice, pinks and crawlers will all have greater portions of their mass as potentially digestable than a young adult male rat on a normal feeding schedule or... Well, the individual comparasins are pretty endless...

Given a sort of constant nutritional value and a constant percentage of the total prey mass as otherwise indigestable, smaller prey items offer greater surface area and will be more fully digested.

As I said though, it's pretty meaningless for most herpers most the time, since a healthy animal given a normal amount of food will digest the digestable tissues pretty well regardless. When looking to put weight on a skinny animal or when dealing with the aftermath of a regurge, the rate of nutrient uptake becomes more important.

I was in the train of thought that pinkie rats were much better than pinkie mice. This is one observation that is emerging in my records. Approx 3 months ago, i acquired a pair of western hognose. The male was 14 and tha female was 9 grams. The female has been eating pinkie rats on average 1/10 days. She like the bigger meal but at an extended rate. The male has only eaten pinkie mice but at a higher frequency. He is currently 26 grams and she is 17. Granted she takes longer to digest the larger meals, he is eating smaller meals but is retaining more mass. This is just a short term observation of 3 months but is does say alot.

The following is the rate of feed for the male.
Beginning weight 14 grams
6-Mar-04 1 pinkie
10-Mar-04 2 pinkie
16-Mar-04 1 pinkie
23-Mar-04 2 pinkie
1-Apr-04 2 pinkie
10-Apr-04 2 pinkie
14-Apr-04 2 pinkie
20-Apr-04 2 pinkie
21-Apr-04 1 pinkie
22-Apr-04 1 pinkie
29-Apr-04 1 pinkie rat
30-Apr-04 2 pinkie
4-Apr-04 1 pinkie
14-May-04 1 pinkie
20-May-04 2 pinkie
25-May-04 1 pinkie
26-May-04 1 pinkie
27-May-04 1 pinkie
30-May-04 2 pinkie
Current weight 26 grams

and the female
Beginning weight 9 grams
22-Mar-04 1 pinkie rat
31-Mar-04 1 pinkie rat
