someone gave me a corn snake, i am not sure what to feed it, it is really small snake about the length of 1.5 pencils and skinny, they told me they put a pinky mouse in
yes, it should be eating pinkie mice right now. you can normally find them at any pet store.
the move was very stressful for your snake. and if it hasn't eaten in four months, it made need prompting to eat. some people will sent their mice with tuna juice, and some people use some other stuff. some people even use ivory soap to wash the pinkie, and it seems to make the snake want to eat it more. another thing you might try is "braining". you take a knife, and slit the head of the pinkie, and squeeze out some of the brains. the scent from this may entice your snake to eat it. if push comes to shove, you could try feeding it live food.
actually the mouse was dead in the cage when they gave it to me,
you should probably clean out the cage. also, when you feed your snake, dont feed it in its cage. take it out, and put it in a shoe box (with a lid. make sure u put air holes in the lid.) and feed it in the shoe box. this keeps them from aciddentily eating substrate that sticks to the pinkie, and keeps them from thinking anything small and pink (like pinkies. or fingers.) that enters the cage is food.
they told me they have not fed it in 4 months but that can't be.
its possible. some snakes can go up to two years without food. however, not as babies. and its never healthy. I'm sure he's hungry. try and feed him as soon as possible.
i filled up its water dish and made sure the heater thing is plugged in,
what is the temperature on the ground in your cage? there should be a warm side, and a cold side. the warm side should be in the mid to upper 80s, and the cool side should be in the mid to upper 70s. If you dont have a thermometer, you can buy temperature probes at wal mart, and other stores like wal mart, fairly cheaply.
but as far as food what to i do? i put a cricket in the cage...
for food, do as listed above. he is not going to eat the cricket, so you should probably take it out.
i hope that helps. good luck with your snake, and welcome to the forums!
