what you're thinking of is a GMO cow !!! those are breeding items.
GMO chickens will give a lioness you feed it to 100% mood and fed to 100% -- it also gives the lioness 10 extra hunts :)

you can buy them in the September in the event shop !! :3 or if you have the funds you can buy them in the trading center but they're usually a fairly high price being a breeding item a lot of people look for!

Sorry, one last question, how do you get GMO cows?

GMO cows are only obtainable through the September event (unless bought from another player)

This thread is old, but as it has been brought back and the OP/other players may benefit, I just want to add: A GMO cow (or other random mutation items, such as lion meat) will not increase your chances of a hybrid any more than any other mutation, even if you are breeding to a hybrid.

It is best to breed directly to a hybrid female using a buffalo scrotum for the best chance of a hybrid. Some players offer reverse breeding services for their hybrids, especially this month. I highly recommend taking advantage of those if you are able, rather than gambling with random mutation items, which are very likely to result in a common mutation.
