my frog doesnt eat until hes sick. he might eat a couple then move on to the water dish. im sure the water dish will dry out and/or get dirty from sitting within 4-5 days so im not sure how to help you there. you dont have a family member or a friend who can come over and check up on your frogs? maybe get a cricket keeper and have him/her throw a few in there for you and change the water and give it a quick mist. even if they can only do it once out of the 4-5 cay period that would be better than nothing. 1.5 days isnt too bad. ive left mine for about a day and everything was ok when i got back. an automatic mister would help a lot but i think they are pretty expensive. maybe a neighbor can come over and spray him? or someone trustworthy?
