Hiya, welcome back to CS!

You can view the pets on your wishlist that another user has open for trading offers by scrolling to the bottom of their open groups in a trade. ^^
Once you initiate a trade with another user:
Select add pets (on the "Things you want from Username" side) > view group: "Pets on your wishlist"

If the other user has no pets available that are on your wishlist, it will read as noted above "(0 pets)".

You can view the pets that you have that are on the other user's wishlist by scrolling to the bottom of your groups in a trade: add pets (on the "You will give these things in exchange") > view group: "Pets on your partner's wishlist"
