I have a lot of geckos of different species, two bearded dragons and a trio of RETF. Normally I'm around every day for the care they require. I would say that 4 days without care is my absolute maximum and done only occasionally. I don't see that it has had ill effect. If I'm going away for a weekend (36-48 hours) I feed/water/mist everyone just before I go and as soon as I get back. On the rare occasions that it's 4 days everyone has been OK (the dragons often don't eat for several days even when offered daily). For more than 4 days I hire someone to come in and do the care. Of course, caring for reptiles and amphibians only every 4 days on a regular basis is not a good idea, but I feel that a monthly 4-day absence is do-able and would be even better if someone could come in midway into the period and do some basic care.
