Well that may have been the issue. He may have just dranks before I took them out. His mouth was closed all the way, and I haven't heard anything coming from him. The female has what sounds to be like a little respiratory thing going on. Nothing bad. I can't hear it all the time. Just every now and again I will hear her make a sound as if she was trying to blow her nose, but it is not with every breath. Just when you hear her do the hard breath out. I have them in one of the tubs now that is better heated so I think that will clear up after a few days. Thanks
