I need help with my coastal he not eating . His temps are hot end 38. - cool end 28 . Lights off at night . In summer only . He last successfully feed in May . Try in June threw it back up. Try again a week later with temps raised wasn't interested at all have been able to get him to feed since . I have try feeding him out on the grass which normal works after I let him sun him self for a half hr to 45 minutes . I have try feeding him in his enclosure . Stapling the head of the rat. He has been check for mites and enclosure treated anyway . He is due to worming but I can't get food down him and can't find a worming product I can put in his water. He has lost some body weight and has a yellowish look to his under belly. He also feels soft when handling him. His breathing is normal .
