I think every person has their own views on frozen vs live. On this screen shot it looks like to me anyways he is suggesting to another keeper on how to switch their snake to frozen thawed. While every person and keeper has their own veiws on it. Both are correct. I know that jumbo rats live can cause serious damage, frozen or live. Therefore I don't feed jumbos. If the snake is too small to be eating a large or jumbo rat yes it can cause serious damage by rupturing the stomach or intestines and creating and internal infection. This will happen frozen thawed or live. Really to be a good keeper you must know how large of prey to feed, and do it safely whether you use frozen or live. And know how to provide for your animals. There is nothing wrong with either way. It doesn't appear to me that the snake in the pic was fed to large of prey but you cannot also really tell from that picture. It certainly didn't die because it was fed a live rat. If the prey was to large then that is a faulty keeper. Most prey that is eaten that is too large will not even be swallowed or it will be regurgitated. But this isn't always the case. Just because a snake looks big enough to eat a jumbo rat doesn't mean they should be. I've never used jumbos on even my largest girls. I feel that jumbos are way too large for a ball python and I don't use larges either. The largest meal I would use on even one of my big girls is like a decent sized medium. But I go for smaller meals fed more frequently. Anyways it appears there was a misunderstanding in some way. Now that we all agree that either way is no better than the other we can move on from the squabbling.
