If you lose them, you lose them. Contact the companies via email if the problem really bugs you though.
They are just on your farm at a random day and time.
you cant simple
It just comes in random.
You can get cows on Farmville when your Farmville friends gift them to you or by adopting them when they wander across a neighbors farm and that neighbor posts a notification about it allowing you to adopt the lost cow.
Go to "lost and hard to get things on Farmville", then send messages to your friends giving them gifts and have them send a gift back to you that you want. Do this until you have all the items you need.
it is there in your gift box
Lost animals occasionally wander onto farms while people are playing Farmville. When this occurs, the owner of the farm has the option of trying to find this animal a home by publishing the story to their profile. The pet can then be accepted by the farmers Facebook friends.
Lost animals show up randomly - there is no telling when they will appear.
If you mean farmville on facebook, then you just have to log into your account. Your farm will be intact
you don't! you just have to adopt them when somebody finds a lost one on their farm.
You can adopt one if any of your Farmville friends encounter one in their farm and post it in their page. To make your search easier, on the left side of your Facebook homepage where there's a list of categories, click 'More' and then there you'll find Farmville. It then will go to the page where all the Farmville status are being posts by you and all of your friends. Try scouring all of their post and maybe you'll be lucky to find a lost cow posted by one of your friends and be able to adopt it.
Ive noticed that usually if you keep your farm up long enough they will wander on...like even after you are done harvesting just keep it on your farm and you should get one.
