Yearling Ball Python Not Eating

[Stewart_Reptiles]

thx for responding!
She was about 700 grams when she stopped eating and now she is 583 grams. She never skipped out on eating before this.
I took her to the vet and they said they didnt know what infection it was, the scales on the belly when rough and sortof flaky a bit like scale rot but they said it wasnt that.
Cage is 35 inches lenghth, 15 inches width and 14 inches high. She has 2 hides, one on the colder end and one on the warmer end.
I'm measuring the tempurature with some tempurature probes about 1cm from the bottom and it reads 24 to 26.5 degrees celcius on the hot end and 23 to 24.5 on the cold end.
I feel this might be hot enough but im not sure if it's different with a heat mat or not
thanks

Those temperature are way off if they have always been this way I am surprised you never ended up with a regurgitation.

2 things I would do is address those temps 26 degrees should be the temps on your cool side not the hot one and your hot side should be at 31 degrees, next I would downsize her to a 20 gallons tank.
