Extend life for cows and sheeps

[Speciekuip]

Please make cows and sheep live twice as long.

 

Can there also be rules to prevent that players livestock end in a other players fridge? I have a walled of yard trying to get good cows with all the green genes. I have seen a couple of times players shooting my livestock. Yesterday i went offline having like 15 cows and bulls and 6 calf with good genes. Today i went online and there is like 6 two day old cows left... Must be a jealous hunter..

There is no hole in my fence so they cant escape or something like that.
