I was thinking about this for a while and I think that it is time to propose this idea.
Most people are looking for C$ around the time that new store pets come out. I spend several hours looking through the C$ shops for pets that I want. What if there were a page that everyone's pets that are up for c$ were put on a tab like the pound. There could be two possible ways for this.
1. a timed "auction" highest bidder
2. Set price and the first person gets the pet.
so If there is the first one, it would be a set amount of time with a fair amount of C$.
If it is the second one, you set the amount that you want for that pet and the first person that sees that pet and is willing to pay the price gets the pet.
You will get your C$ if you set that pet up for auction for offer. This part will end up being like a trade. They get the pet and you get the C$.
Please voice if you want this to be a possible option for a far in the future update. Every voice is appreciated.
