No problem thats wonderdul! Yeah the carpet seems like the best way to go but from experience its almost just as bad as sand but for other reasons...even if you dont let them poop on it, so much bacteria collects in there and they are almost impossible to clean. Also remember that if either of the BDs appetites stop or lessen just to be on the safe side collect a fresh poop and get a fecal exam done by an exotics vet. it only costs 67$ at my vets (who are normally on the pricey side)...and if its parasites it will be the best 67$ you ever spent if not 67$ is a small price to pay to save you BDs life. Things to look for to determine parasites other than lethargy and lack of appetite is: droopy dull eyes (their eyes should normally look deep in colour or bright in colour like marble), dark shades in their colours and patterns that arent their natural colours (provided they arent cold from low temperatures:that will make them dark too), white or black gums or any colour other than pink; you want nice pink gums, or any other discolouration in their mouth, sickly looking poos if freshly made, abnormally long time to actually push out the poo, and looking skinny such as no fat reserves like the lower body belt of fat and the two spots underneath their "armpits". Thats one way if i know to worry about my BD if she isnt eating...if she still has her fat reserves i know shes not malnourished and has something to live off of. You have to remember eventhough BDs are now captive bred they still have that biological imprint in their mind to be opertunistic eaters meaning they really dont believe they know food is coming regularly so they eat anything on oppertunity so thats why you need to know your BD because they will either interpret that as they need to eat as much as possible (the good eaters) or they just dont !believe! intuatively that they really need to use their energy to consume that food frequently (finiky eaters). Thats why the finiky eater will occasionally (maybe once or twice a month) gorge and eat 50+ worms in one sitting and a plate of veggies because they know their body needs it if its getting low on stored energy aka fat reserves. So just know which your bearded dragon is. Also dont be afraid to 'force' feed (without harming their gums)...however only do this when you have their complete trust so you dont inadvertantly either make them aggressive or fearful or both. A good way to tell is how much you can fiddle with their tail, hands, beard, etc. As well as try and see your BDs reaction to your hand SLOWLY going 2-4inches over their head when they are out and on your lap or bed/couch. And lastly a good trust test is as silly as it sounds see how comfortable they are with their face close to yours even try kissing them repeatedly and regulary because no untrusting animal will put their face near anythings mouth.
