Jon Katz has always emphasized the otherness of animals - the need to avoid anthropomorphism - the requirement to accept animals as animals.
He seems to have abandoned his principles and is taking the sound of bleats personally. What sound was he expecting from a goat?
I'm not there, but it sounds like his goats are asking for more of Katz's participation in their lives; more visits to the pen; (for all I know) a game of fetch or headbutt.
