First time snake owners. Thought we were doing really well, now not eating and has patch of broken scales near neck. Here's her history... dob 19/12/21. Shed 5/1/22. Pinkie fed by breeder Jan 6, 9, 16, 18, 19. We picked her up 21 Jan. Breeder gave us the tub she had been using. Took pinkies from us 23 and 25 with no problems. Has not taken anything since, and appears stressed (heavy breathing, constricting, urinating on us...) Tried feeding her again tonight, totally uninterested. Noticed missing scales on side of neck. A few days ago we thought maybe change of character may be because of shedding, but has not had cloudy eyes, or pinkish belly or any other "signs" we've read. So has been a week since last eaten. Tub has water, heat mat under approx 1/3 with thermostat, a warm and a cold hide. At what point do we start worrying? We are in SEQld, very warm and humid. Should I be getting scales to monitor weight? Or am I over worrying...
