Just a question of curiosity: What is the oldest anyone has had a cow reach? Or heard of? I ask because I have a cow that my dad bought as a calf when I was a teenager. She has to be 15 years old. She looks old, but she gets around, isn't suffering, and is actually doing well (all things considered). I confess she is a pet more than an investment like the rest. It just got me to wondering. Thanks.
