Pardon me for offering a slight correction. These 2 products are NOT identical, besides one (chlorhexidine) being a generic name & the other (Nolvasan) being a trademarked & slightly modified version of chlorhexidine; the important difference to note is that chlorhexidine has very little effect against viruses, whereas Nolvasan does. It's a slightly different chemical configuration that makes the difference- & a big difference in cost. I used to use Nolvasan (when I had way more snakes than I currently have, & included both rescues & some breeding), but I no longer do- I use generic chlorhexidine (& FYI, I currently keep 19 snakes, with no plans to add any- I also use it for my rodent cages). Nolvasan is more typically used in veterinary clinics & other professional locations- & they can write off the cost as a business expense also.![]()
