DAY 8: Well, any complications with this hatch will definitely be as a result of the operator of the incubator, not the incubator itself! Temperature holding steady at 99.5 F, but humidity's fluctuated some, between 50 and 59%. Our new kitten decided that the tube that runs from the water bottle to the pump would make a terrific play toy, and pulled it out and chewed it in half! *Sigh.* This is why kittens are cute. . . so we don't kill them.
No real harm done, though. The tube couldn't have been out of the bottle more than a few hours before we noticed it, and the shortened tube still fits in the bottle as long as we keep the water level high. We'll hit up the hardware store this weekend for a replacement length of tube. I had to run the pump a bit to get rid of an air bubble, which bumped the humidity up to 59%, but it drifted back down to normal levels (53-55%) pretty quickly.
Now we just have to figure out how to "kitten-proof" the bottle and tube assembly!
