Trying to get four of the same legendary pet to make a neon can literally take forever if you rely on luck alone. I was stuck needing just one more pet to finish my set and finally gave up on random trades. Decided to buy adopt me pets through a site to just get it over with, and honestly, I should have done it sooner. The process was completely seamless, the interface is super clean, and I had my pet in my inventory within minutes.
