If there weren't already an overabundance of cats available at every shelter, I would say that your idea is actually plausible.
Internet sites like imgur could offer you discounted cats provided you were only able to upload funny videos or pictures of them to their own website, ensuring they get the resulting traffic.
It's not that ridiculous when you think about it - certain breeds are worth ridiculous amounts of money - how much longer until we see genetically engineered proofs of pedigree integrated into the DNA of the cats themselves? Perhaps something to stop you from breeding more?
