I bought a UC for 25 dollars a bit ago, and I'm pretty happy, since it's higher valued (in terms of UC trading) than alot of other pets at similar prices (according to our UC values thread). I have an offer of a 75 dollar pet (which I've been told to reject), and I'm just wondering, how these prices are influenced? Is this inadvertent, or are the prices meant to be like this?

My pet is rare-ish too, so I thought that would make it more expensive, since it would be more difficult to trade and not just be another one (for example) the 100 uc baby kougras uft every day
