Green Anole

Question
One just showed up in my office.  The first month I didn't do anything but watch, then I started misting the ivy plant it lives in and feeding it crickets every other day.  I respect wild animals and won't try to touch it or anything.  He has been in my office now about 4 months.  Any tips to keeping it healthy in this environment.  It lives in an ivy plant on a window sill.  It rarely leaves the sill.  I did put paper towels down to keep it a little warmer from the metal sill.

Answer
What size crickets in comparison to the lizard's head? The standard is not more than 1/2 the width of the head, and the smaller the size the safer. This is also a pretty tropical lizard, so I would place a small saucer of water there as well among the plant to give him someplace to soak in relative privacy.

He's come in for winter to retreat. This is common this time of year for small geckos and anoles in Texas. If you don't know how to hibernate a reptile, then the only thing you can do, is do what you can until Spring arrives and after last frost let it outside. This would be best for him, as he can't live that way in your ivy long term, but to let him out now would not give him good chances that he gets situated before the next hard freeze. I'm only a couple of hours north of Dallas, and despite the warm trends here and there, it's still too soon to turn him out.

Take care that he has plenty of shade from the Ivy or a little hide box, as sunlight through a window will magnify the heat and on a warmer day it could cause the lizard to go into heat stroke if it can't retreat. Also, he will be UVB/vit D deprived being held this long without unfiltered sunlight, so I would recommend that if you are going to allow him to remain there, that you dust the crickets with a SMALL amount of vit D3 calcium dust. Normally I wouldn't advise a D3 calcium supplement, because it's not as safe as a UVB lamp and overdose because it is a fat soluble hormone can be a problem if you use it excessively...but unless you want to buy him a UVB linear lamp to mount to the side of the sill LOL...

Is the surrounding otherwise safe? You don't have janitors that might shoo him out or accidentally step on him, or office cats do you? I'd appreciate attachment of a couple of pictures of the plant and the lizard to have a look.

Alternatively, it might be safest for him to go to a terrarium for safe keeping until spring, but this will involve you buying a few things. There's a tradeoff here. He's probably happy there, but also I would assume he's at some risk in an office environment, being a little lizard, and he's probably very badly wanting out through that glass as a reason he stays there. He might initially be a little more stressed out being confined, but it's a question of where he would be safer...you've got a good 2 months to go, at least, before he's going to be safe to go outside again, so I would just worry that being exposed in an indoor environment, more than likely something bad is going to happen before Spring gets here.
