only 2 of my 4 balls are eating right now. one just took his first meal in 136 days. and another just hit 200 days. yes i was worried but i know they'll eat when they wanna eat. like Dr. Del said i keep a close eye on thier weight. my male who's been off feed for 200 day only lost about 100 grams. i think something to take into consideration before anyone panics about an off feed ball is there size and feeding habits before they went off feed. mine are all big enuff to go a long time without too much worry.
