Or not get one at all as they see it as "waste".
Not really the right wording on a beardie forum, where everyone adores their pets, and would sell their souls to keep up with the costs of looking after their Beardies.
If you are worried about cost, then A BABY BEARDIE IS NOT FOR YOU.
Adult Beardies eat 20% live feeders and 80% fresh veg. (try telling Dexter that!)
You CANNOT feed a beardie rice, only "meat" they are allowed is insects.
Without being rude, you need to do a heck of a lot more RESEARCH before you buy a bearded dragon.
As for going to the vets every 3 - 4 months - I don't think that is necessary unless your beardie is constantly in contact with the outside world, or you regularly feed crickets that have parasites? (unless you meant at AGE of 3 - 4 months?)
Surely if you are immaculate in their hygiene, NEVER put something in the enclosure from straight outside, and avoid crickets like the plague, your beardie simply can't get parasites?! (providing you don't have other animals that go outside in his enclosure, or touching him, or crapping on surfaces that your beardie touches!?)
I certainly won't be taking Dexter every 3-4 months! Surely it's not necessary if he NEVER comes into contact with something wild?!
My cat only goes once a year for his annual vaccinations and a general check up!
(he's an indoor cat - only time he ventures outside is in his carrier, to go to the vets)
