I got my ball October 21st 2018. I would guess she is about 1 year old. I’ve fed her once a week every week since then and she has always eaten. I’m on frozen rat 7 of a 15count bag of food and she won’t eat. She’s now missed two feedings; has not eaten since aug 1st. I’ve double and triple checked her temps and everything is the same as it has always been 80cool 90hot. I use two thermostats and two heat pads. Her last shed was ~3wks ago. How long should I wait before getting a vet involved?
