I already suggested this, and unfortunately, it was shot down by angel, and here's the exact message I got:
"this is a question of balance between breeding and taming. Ability to throw out wild pets after they have been just caught will make breeding senseless, users will just roll wild pets until they get the one they want. We would have to change our tagline to "pet taming game" in this case :)
Pet limit is a kind of stimulus for a player to develop and figure out some tactics instead of getting everything at once.
The main way of getting recipes for building supposed to be finding them in treasure chests and trading with other players, not buying in the shop.
The main source of income is quests. Fulfilling one silver quest every day will make in average 25-30K of coins in 10 days. Silver quests don't have genetic requirements, only characteristics which are growing with pet level and not so hard to achieve.

Hello there! My name is Shadow, and I specialize in the collecting and breeding of gryphons. If you'd like to breed with one of my males, or purchase any of my non-gryphons, just shoot me a message!
