Why aren't my corn snakes eating? Is it mating or their new lights?

Check the temperature in their enclosures. Low temps can affect appetite and activity in reptiles. If you keep them in the same enclosure, consider housing them separately to avoid stress or aggression. Survey the area in and around the enclosures for any negative stimuli. This may include loud noises, strong vibrations, bright lights, cold drafts or high traffic. Reduce or eliminate any if found. Letting them out on the lawn or in the garden is not recommended as they could escape, get injured or pick up parasites.

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.

Check the temperature in the enclosure. Low temps can affect activity in reptiles. Survey the area around her cage for any negative stimuli. Reduce or eliminate them if possible. Corn snakes are mostly nocturnal, so she may be more active when you are sleeping.

Thanks for reaching out about your ball python. Seems like your husbandry is good. Intestinal parasites are common in snakes, more prominent in recent acquisitions. A fecal examination by a veterinarian is probably the first idea. Metabolic disorders or systemic infections are other possibilities. Good luck.

The changes to his enclosure may have caused stress. Low temps can affect digestion in reptiles. If temps were down, this could affect defecation. Try soaking him in a warm 50/50 solution of water and unflavored PediaLyte for 20-30 minutes. This will provide warmth and hydration. To stimulate defecation, gently massage the belly from front to back during the soak. If the behavior persists, consider an exam with your veterinarian or vet experienced in treating reptiles.

Thanks for reaching out about Charlie and including the history. Your husbandry appears appropriate. This could be an extended period of brumation but the only way to rule out problems is through a veterinary visit and some blood work. If you palpate along the body, any masses or lumps? Have you tried different prey items, i.e. rat pups? Good luck.
