Yeah, I remember the Texas rat you mentioned real well. Same with the Cal. King. As a matter of fact, there are many two-headed rats and kings, especially Cal. kings. This is not abit surprising because of the zillions of these that are produced. When you figure in all these that are produced each year by breeder's, logically there would also be a good number of weirdo mutants as well.
I remember the dude auctioning a two-headed albino Black or Texas rat for I think it was some totally ridiculous amount like $150,000 dollars on an auction site..LOL!
A lady friend of mine asked me about this a long time ago, and I told her....."believe me, two-headed snakes are much more common nowadays than you could possibly imagine". People off the street from the general public have no concept of how popular snake breeding is today, and most would probably think these are worth a huge king's ransome(as the guy's auction amount attests too..LOL!), but this really isn't necessarily the case at all. It depends on many factors, and one big one is how coveted and sought after the particular species/subspecies is in the first place. A perectly formed two-headed woma, or Outer Banks king is CERTAIN to fetch many many thousands more than say,...a garter snake.
In any case, they make for an interesting conversation piece, and nothing more. You certainly cannot produce more of these at will..LOL!
