How often should I feed my corn snake to stay healthy, not overweight?

Hello! Snake feeding requirements are more based on size and weight than on chronological age. So generally, yes a corn snake under 1 year should be eating pinkies and older corn snakes will typically start eating small mice, then larger mice, it can depend on the individual. I would recommend taking Franklin to a reptile vet for a wellness/new pet exam and they can give a much more specific feeding recommendation based on their exam findings. Since I can’t see Franklin, it’s hard for me to give you a specific instruction about size and number of mice or rats to feed, though I suspect that he should be eating more than just a pinkie every 2 weeks. Good luck!

An adult corn snake should only eat once every 7-10 days. Here’s a helpful rule of thumb that applies to most snake-feeding situations. It relates to the size of the prey items. You should offer your snake feeder mice or rats that are roughly the size of the snake at the snake’s widest part (the mid-body area). In other words, the feeder rodent should be 1 to 1-1/2 times the diameter of your snake’s middle. You can go slightly larger than this, but not much.

Thanks for reaching out about Ivory and including a photo. You are correct that snakes can be finicky eaters during weather changes. If you feed mice, try offering rat pups: to snakes they smell and taste differently. If that doesn't work, a veterinary visit is recommended as intestinal parasites or infections are common. Good luck.

I honestly would not be overly concerned at this point. Snakes can go for very long periods of time (months) without eating at all. At least he is still eating something. He may be getting ready to shed or possibly the tank temperature has fallen too low. I suggest you check the temperature of the tank to make sure it is staying at the correct levels. There should be a temperature gradient of 70-85 degrees so that one side of the cage is warmer than the other. That way he can move around to the temperature he needs at any given time. When they are digesting their food they often need higher temps. After making sure the temperatures are correct, I recommend skipping one week of feed all together. Then the next week, try feeding him again to see if his appetite is back to normal.

Thanks for reaching out about Francis. If the stool appears well formed and normal otherwise, monitoring the situation is appropriate. If Francis is showing any behavioral or other changes, a veterinary visit is recommended. Good luck.

Corn snakes can grow to as long as 5 feet. On average, they grow to 3-4 feet. A 10 gallon tank is too small. At minimum, a 20 gallon enclosure is recommended. A temp range of 75F-85F is best. They do not "need" a UVB light source but seem to be healthier with one. At 2 years of age, it should be eating adult mice. If it can't, feed whatever you can to get it back into a positive plane of nutrition so it can grow properly. Consider an exam with your veterinarian or an experienced herp vet to diagnose and treat any pre exiting conditions. Submit a stool sample to diagnose intestinal parasites.

Average adult weight can range between 600 and 800 grams, although an adult can weigh as much as 1500 grams. Have her examined by your veterinarian or a vet experienced in treating reptiles first to confirm good health and weight. If necessary, you can feed her twice weekly until she is at a healthy weight.
