5 crickets a week???? im sorry, but i have had chams before, and i have never fed them only 5 crickets a week..........thats keeping them a little more than just "hungry" in my opinion.......the last veiled i had lived to be 6, and he ate at least 5 crix a day.........
We have to stop humanizing these animals, reptiles have a completly different metabolism then we have.
You need to consider that the density of food in their natural habitats fluctates seasonaly, meaning that their are times, where they can stuff themselves and times where they will hardly find anything to nibble on.
Thus in their natural habitats those individuals, who eat as much as possible during the season rich of food, will have better chances surviving the season with little food, because they can live of their fat depot -> thus have a higher fitness(can bear more offspring).
No we take the chameleon from it's habitat and stick it into an enclosure.
The genes of the chameleon still "say" <<eat as much as possible>>.
And if offered food, it will eat and eat and eat and eat... (since this has worked in the wild)
If offered larvae often (that contain a lot of fat, that they need in order to go through their metamorphosis) which chameleons will most seldomly find in nature, but turn out to be good way of getting some extra calories, they start to get picky.
In order to find prey chameleons often have to activly go hunting, in captivity they can comfortably shoot their prey out of a bowl, hardly having to move an inch, thus saving energy.
Consequences of a diet to rich in protein and fat?
The concentration of uric acid (emerges during the processing of proteins)
in the blood rises and if the saturation point in the kidney is reached, the uric acid crystals are stored in the joints or the guts -> the limbs appear swollen and it hurts, so the animal appears to be lying on the branch.
Reptiles are survivalists, it is very difficult to feed chameleons too little, the animals will just lower their metabolism and move less.
An example from a keeper I know, who took over over a male panther chameleon length head2tail 43cm weight 210g, that iho was formed like a football. He let him starve for 4 weeks (only gave him 5 crickets and a few fruitflies). In the first days he could observe the chameleon activly searching for food after a week or so, he just sat there and waited. The result was, that he hab only lost about 5grams ^^
