I would hope they are educated so dont do wrong again, or dont own other reptiles. This poor monitor sounds like teh result of an owner not being equiped with teh right knowledge, and I hope was not doing what was just convienient for them.
Unfortunately, as has been mentioned (thanks Brendan), this was not the case. I saw the animal in this thread, when it was young and still owned by the previous owner, as he brought it over for me to have a look at. The first sign of trouble was when he said 'it handles well' and it was only of hatchling size, yet had hatched the previous year. I gave him a really detailed care sheet, told him to only feed it small whole animals, suggested a number of improvements necessary for his enclosure, particularly warning that having a wire mesh enclosure indoors is a really bad idea (it leads to skin burns).
After all that, he figured he knew better and did things his way, regardless. On top of that, even after he sold that monitor and Brendan (RSPcrazy) posted photos of it here in its current state, the original owner contacted me because he was upset I was speaking ill of him as he refused to admit the monitor's poor health was his fault. My favourite bit was when he kept telling me that he didn't just give it just
any chicken meat, but only the 'best' chicken breast available in Woollies' meat department.
It gets worse. He contacted me again a few months ago, telling me he wanted to get back into keeping monitors and asking if I had any to sell. You can guess my reply (I can't repeat it here, for the profanities would get the post removed). I don't think he should ever keep reptiles again and pretty much told him that, in more colourful language. He then said he'd learned his lesson, had realised his mistake and it didn't matter if I refused to sell him one because he was going to get a monitor from someone else anyway. I then said if that were the case, could he please send me photos of his 'new and improved' enclosure so at very least I could give him advice to make sure he didn't repeat his mistakes. He was really happy I suggested this and said he'd send me images right away.
Still waiting for those photos, of course.
