I have 2 corns but have been thinking on expanding to the ratsnake world and got a few questions:
1. what is the average size? I was told their a bit longer and thicker then corns.
The corn snake is in the rat snake Genus, and is a rat snake. So technically you are already in the ratsnake world. LOL
As far as avererage size, that depends on which rat you go with.
The smaller rats would be the gray rat, yellow rat and possibly the green rat. They all average 4'-5', and the corn snake can attain lengths exceeding 5'. So the gray, yellow and green are about the same size as a corn. The larger rats would be the black rat, texas rat and everglades rat. The black rat can get up to and exceed 7'. The record black rat snake is 108" long!!
The black rat and texas rat do get pretty hefty.
2. temperment? for the most part I am under the assumption about the same as corns
Texas rats have the reputation for being down right nasty sometimes. I have never owned one and cannot tell you from first hand experience. However I have 2 black rat snakes and they are both just as docile as my corn, and the oldest is a W/C specimen. I have had him since a hatchling, so its almost the same as having a C/B.
3. care? again I assuming(I know that i shouldn't but thats why I'm asking) not much different then corns
Yes the care is the same for rats and corns. Of course the ratsnakes I have named are all north american rats, and the foreign rats are different. I have never owned any of the "old world" rats, so I cant relate any experience.
Hope this helps.
