Ok, I'm sure there is probably another post somewhere on this site that is similar to this, but it's late, and I don't want to search for one tonight! So here's my issue:

This past Christmas (2012) we somehow managed to bring home a Pacific tree frog in our Christmas tree. How he stayed put through us cutting it down, dragging it up the hill, putting it through the binding machine, setting it up at home and getting 3 strands of lights on it, I'll never really know, but somehow, he did. The kids were thrilled and we decided to keep him. We got him a nice enclosure and he's got plenty of climbing and hiding places along with a nice sized soaking pool. He's been a pretty happy little frog. He's also been very vocal, making his presence known at least once a day, everyday. Until recently. It's been about 10 days since he's made any sounds other than a little chirp that he makes when he catches a cricket. We're starting to get a little concerned.

We have tried to think of what could be causing it, but the only things that we've come up with were that it started within a day or two of us getting a new batch of crickets; or the water we are using for his pool and to mist him. As far as the crickets, we buy from the same store all the time, so I don't think anything would be different as far as where they come from, unless the store changed their supplier. We feed the crickets with Fluker's and give carrots as a water/additional food source per the recommendation of lady at the pet store. Hmm.. Now that I think about it, the new batch we got was the first one we used carrots with. Great.... so now I have a new variable... Any thoughts on that one? And with the water, we use tap water and are on city water. Could that be an issue? I didn't even think about it until just this last week, but I know our water is treated. Should I switch to distilled?

Anyway, so those are the things that I've come up with that maybe making him sick. But I don't actually know if he's sick. What's normal and what's not as far as him being vocal?
