>>Okay. I'm going to be painfully direct.
The amount of calcium alone bothers be for a growing snake. All I could get from the producers is that it has "enough calcium." I asked what theat means, and they were like "you know, enough. I promise."
Yeah, right. I don't agree with that for sure. My best suggestion, if you must use these, are to alternate then with good healthy rodents....if your snake will even continually maintain them. The feces all look like it came from a sick snake when they feed on thiose, though: wet, smelly, moist, etc. So, that idicator will not help you make sure your snake is still healthy.
We'll sell help get snakes on those for others (and customers) - but we strongly urge against it - as long as it is a snake they don't plan to breed, brumate, etc.. Any problems with it will be worse in an animal subjected to those stresses. Try calling T-Rex and asking about a local distributor in your area. That's the only way I've evenr found any when I was experimenting with them.
