One of my cats tends to sleep on the top of the bed, and picks the side in an apparently random way. This means it would block the sensor on something close to 50% of nights.

Cool product though, and this is a pretty specific issue (e.g. the other cat prefers sleeping in the legs, or under the bedsheets).

Thanks. Very interesting feedback, that's something I didn't think of. You know, a cat's body temperature runs a couple of degrees hotter than humans. I don't think our sensor is quite that narrow in its tuning range to discriminate between humans and pets, but maybe we could do that on a future version or slightly more advanced technology. Just a thought, I'm not guaranteeing that we will do it, or that it's even possible without extremely expensive thermal sensors. Hopefully, the issue you described is not common enough to be a problem for most people.
