I had something similar with my baby he ate when I first got him home then didn’t eat for 3-4 days, I thought there must have been something wrong, but he was just settling in. I did make the temp a little lower as the breeder said it was a little high for what he kept them at but he started with a sleeping pattern and with his own little routine in the morning and then bang I wasn’t finding any locus in his viv and I have never been so released about anything. The people on this forum are really good and help me when I posted something very much the same! I hope you get your baby to eat and wish you all the beat
