Hi all. Hope you can help me, and please tell me if there's a better place on here for this post. I spotted a tree frog, maybe 1 1/4 inches long, on the floor of the outer lobby at my job. At first, his back legs were splayed out wide, and that looked wrong. So, I went to get a cup to bring him in. When I returned, his legs were pulled close to him again, but I brought him inside. He's not very mobile at all. Once in a while, he'll blink his eyes a bit, or nod his head up and down for a sec, or shift his legs just a little. Sometimes he looks like he's swallowing. His belly is sticky, which I know is normal, but I don't know if this helps us know anything about his general good health. His front legs look a little...thin...and I don't think his toes are very well separated.
Because I've heard of frogs suffering from drying out, and I've seen tiny black frogs inside our building seemingly petrified and stuck to the floor, I carefully dripped little drops of bottled spring water onto his back, sides and legs with my fingers. Am I right that he gets his water through his skin, rather than by drinking? Should I try to feed him anything? Is there anything else I can try to do for him? We do have stray cats all over the place here, but I don't see any punctures or blood on him. (Would I see red blood?) Any advice is appreciated.
