Will a California king snake over eat?
No - they will only eat when they're hungry - as other animals do. They wouldn't 'gorge' themselves if you just kept offering food items.
Any pet shop owner that is selling a captive bred snake, that ethically they all should be, that tells you that the snake will not eat frozen mice, should not be allowed to sell reptiles as this is absolute nonsense. If of course you don't have a captive bred snake, and one that was taken directly from the wild, I suggest you think hard about the consequences of encouraging the sale of reptiles in this…
From a biological perspective, California King snakes are very opportunistic feeders and eat a large variety of prey. They may take fish if more preferred prey were unavailable, but would likely choose warmer food first. From a hobbyist perspective, I have never heard of anyone offering a pet King snake fish and have no personal experience with this particular issue.
I think king snake . Indigo snakes are larger than king snakes.A king snake normally grows 3-4 feet and the maximum length reaching 8-9 feet. An indigo snake normally grows to 5-6 feet and its maximum length can row up to 8 feet. Another plus point of a king snake have the ability that they are not affected by venom so the king snake will win the battle and will eat the indigo snake…
Depending on how big the snake is. Most snakes eat live white mice but will eat frozen ones if that is what you are offering them. Snakes tend to eat once one or twice a week depending on their size. A lot of owners will maintain their own little white mice just for their snake or buy them frozen from a local animal store.
It will depend on the size of the snakes. A kingsnake can kill a snake larger than it itself but may struggle to consume a snake that is larger than itself. It is certainly possible that it will be able to kill and eat a snake larger than itself though and i have witnessed it. It is just very rare since the king snakes (Lampropeltis) prefer to take smaller prey for ease.
