new owner needs help

Ive had my python for about 4 months and he is about 5 months old he USED TO eat every 2 weeks but all of a sudden he hasnt eaten for 37 days. he eats live mice he is 22 inches and i have NO IDEA what to do!! Someone help me!!

what size tank is he in? is it a male or female? what are the temperatures and humidity??? whats in his tank?

Post a pic of your setup :)

Maybe im wrong but once every 2 weeks is a big strung out isnt it?
Check all your temps, humidity, and hides. If all are ok, then i would try A) different prey switch to a fuzzy rat or hopper which ever is the proper size for you. B) take it to the vet and check for any parasites or other health problems. Goodluck. Please keep us posted on progress. :)

Posting your set-up, currant temps, humidity, etc is the only way that people could advise you on why your snake may not be eating.
There are many reasons that snakes refuse to feed, but they range from mild to serious problems, and without information, we can't help.

WOW! 5 months and only feeding every two weeks, probably should be eating once a week.

A good rule for feeding is: Every 5 days until 100g in weight, then every 7 days.

We'll have to know all the specifics of your setup:
What type of enclosure? (tank or tub)
What the temperatures are?
How you're measuring those temperatures?
What the humidity is?
What substrate you use?
What your heat source is? (UTH, heat tape, lamp)
How you control that heat source?
What food you offer to the snake?

I know I forgot a few, but you get the idea...we would have to know everything about the setup to rule out husbandry issues as a cause of non feeding. Other possible causes are parasites and sickness, or simply a winter fast. It could be almost anything, so the more information you give us, the better we can help you out. :)

watch the weight of the animal, if its not losing any or much, dont worry about it and wait till the weather starts warming up a bit more and your snake will probably eat then.

Sometimes they stop around this time of year. So long as they arent losing much weight, i wouldnt worry about it.

Possibly the winter cold.
