Locasio, of course it is more then cricket bite, it is infected. you should should stop that. thyme is seeking for advice and help that is what he should be getting, not pointing fingers, no need to be so rude. yes frogs don't drink like we do, they absorb water though their skin, not everybody know that, that is what the forum is for to ask questions and seek information.
I'm sure s/he can take care of the frog and is trying to help him now, s/he wrote that the wound is looking better now, we all started somewhere and had probably stupidest questions then, so relax and if you can help please do so.
