I love a good devils advocate!
To answer your question, it depends ... are those animals being sold at "dirty cage prices"? cause if they are ... boy oh boy, I might just be tempted!
Ya know, for the life of me, I can't figure out a way to wiggle out of this sticky wicket with grace ... makes me want to go downstairs and take some pictures of dirty cages and post them up

... Do I wish every breeder/keeper (including myself) always had clean cages ... absolutely ... Do I realize the impossibility of that wish? ... absolutely ... But, with all of the animals that I've bought and all the money I've spent, I can say without a doubt, that not a single one was chosen from a picture of the animal in a dirty cage or picked out of a dirty tub at a breeders facility. Does that make it better? Maybe, maybe not. But if I personally have to start somewhere, for me, holding the presentation of a seller (ANY SELLER) that is presenting an animal for sale to the public to a little bit of a higher standard ain't a bad place. Once I climb that Everest, I'll move on to the next one.
How was that for a mega weaselly answer?
And with that, I'll return to my dream world of clean cages and cloacas hand wiped after every BM before I manage to shove my foot ever further into my mouth.
