stopped eating

I feed my snake every 7 -10 days depending on my week. this was working good but the last couple of times I have offered my snake wont even bite. Wednesday was 7 days and i offered a couple times (frozen). yesterday i tried the same thing and evn resorted to live but the snake wouldnt even go for that. i killed the mouse and left it in with him overnight and he STILL hasn't eaten it. What is going on? Is there anything I can do to make him eat more? the snake is about 9 or 10 months old and eats small mice once a week. well.....ususally.

How long have you had the snake? Could it be preparing to shed? Any temperature changes (check, don't guess)?

It is very common for a Ball Python to miss a scheduled feeding from time to time. So if I am reading your post correctly it has been 10 days since its last meal? That is really nothing to worry about. Keep offering him food once a week (not every couple of days) and he should resume eating soon as long as your environmentals (temps, humidity, day/night cycle, etc) are correct.

Keep in mind also the time of year. It's easy for the cage temps to slip and you not realize it. I always have a few that go off feed around this time regardless.
Right now I have 5 or so 1-2 year olds that haven't eaten the last three weeks. They'll come back around before long, but it's bothersome in the meantime.
Seven days is nothing to even be concerned about. Some balls will go twice that long for no apparent reason at any time of the year.

the tank was around mid 80s in the warm side with 40% humidity when i was trying to feed. now its holding steady at 94 with 30% humidity. i mist the cage in the morning and at night. hopefully next week my snake will eat. i saw him come out today during the daytime which was different since it usually hides until night time. it HAS been colder here lately (snow) but i figured with the house set it wouldnt matter enough.

i got the snake last july.

You might try getting the temps down a bit, and the humidity up. Believe it or not, not all boids respond well to high temps. And how cold does the tank get at night? (I guess I should have asked this first - how long has it been that warm?). Sometimes, night time temp drops are enough to throw them off feed.
Oh, you never did say - how long has it been since he ate?

Last time he at was..............calender.............the first of the month. one small mouse. tank usually warms up at night (dont ask me). i have a digital thermometer i reste at night to check that and see if i change anything.

its a 20L tank with a 75 watt heat lamp. without the heat lamp it was 80-85 with about 50-60% humidity. seems like this changed his eating habits.

as its set now if i keep the lamp off it will be around 83-85 but im hoping the warmer temps will make him a little hungrier. thats the impression i have gotten from reading on here.

i tried again today and no luck. I'm going to try on Wednesday and see what happens. This hasn't ever happened before but the snake doesn't look sick and moves around just fine. Looks a little thinner then usual but thats expected from not eating for almost 2 weeks.

tank is holding stable at 92 on the warm side with about 30% humidity and the cool side is 78-80 with about 45-50% humidity.

Forget about trying on Wednesday, lol. Increase the humidity a bit and leave him alone. Don't mess with it any more than necessary for cage maintenance. Give him 7-10 days and try again
