For sure , but where do you draw the line ?
Yes, thats a hard one to answer.
I have a warranty for temprament and health for about a year ( I don't usually bring this up with customers) but it is subject to cross examination on housing and husbandry. I have so far only replaced one reptile in 6 years and it was only two weeks ago.
Only had one unhappy customer ( that I at least know about ) because I didn't offer a replacement but I established he had overfed a hatchling Woma after not taking my advice.
