Is there any point in the future where you will only be living in one house? If so, I'd advise just waiting until that point. If you are leaving a chameleon in someone else's care for 1/2 the time it's very important that they are as interested and excited about having a chameleon as you are. Anything less is not fair to that person nor the chameleon. Also it will be much harder to monitor health issues - if something crops up and you miss it during one visit and don't catch it until the next visit that could be bad. I'm not trying to discourage you, I just want what's best for everyone involved.
