You have to give them lots of Oran Berries.
moomoo
Cows that say "moo" two times in a row.
Likely no. Pokemon are fictional characters. Cows are not.
MooMoo or MoMo it dosent really matter how you pronounce it but there is a MooMoo (MoMo) off the show "The Avatar". It would be an unusual pet to have so i would get it. But he/she cant play games like fetch and cat understand your English
Clay, it is better on their hooves.
Genetics. There's no better explanation for it.
go to olivine city then onto route 29 all the way to the farm (cows) go in give the sick cow a oran berrys until its better when its better get the seals of the girls that are looking after it :D and the seal case
Cows learn where to go for water, when milking time is (for dairy cows), when it's time to switch to a better pasture (for cows that are being rotationally grazed), what feed and grasses are the best to eat, etc.
you can have up to 2 cows on 1 acre of land. but better if you only have 1
Yes they do. They belch it out just as often as cows do. Only difference is that bison are better adapted at digesting coarser roughage than cows.
When cows get pneumonia it can be passed to other cows.
Travel Left of Ecruteak City intil you reach the cows, then go south. when you reach Olivine City, get to the top of the lighthouse without using the elevator, a girl at the top will tell you that the Pokemon is sick and needs medicine, so, using surf, get Cianwood City and go into the med centre talk to the man and he will give you a potion. Take that back to the girl using the elevator this time and she will heal the pokemon. The girl is now in the gym.:)
