There is another emergency situation chameleon owners should think about. What if you became ill or had to leave on an emergency on very short notice? It is always a good idea to put together a little "manual" to keep at home so that someone who has to take care of your chameleon in these types of situations knows what to do. Also, talk to a friend and another family member about this type of possibility and ask if they would be a "stand by" should an emergency occur.
A solution is to type out full instructions of how to care for them, what to feed them, how much, and where to obtain the feeders. Include if they need dusting and how frequently, how to take care of the water system, operating the lighting, how you keep your cage clean and safe, and maybe some signs to look for (such as hydration) if your chameleon is showing symptoms.
Additionally, if you own females to breed as well, have a section about your female possibly laying eggs and signs to look for should she be ready.
You never know what may come up in life and one day you may have to pack your bag and jump a plane for a family emergency or something may happen to you as well (I hate to say these things, but should be thought of). I'm sure the situation would be worse should you come home and have not had your chameleon properly taken care of because someone didn't know what to do or you didn't have a "stand-by" to help if you were ever absent for a period of time from your home.
I'm sure there is more instructions to add to you manual, but give it some food for thought
