Description of your suggestion.

Some (not all) Croptopia crops should be usable as animal feed. Examples:

• 🐄 🐑 Cows & sheep can eat barley or oats (grass/cereal crops)
• 🐖 Pigs can eat corn (and other vegetable crops)
• 🐈 Cats can eat roe (and any other fish product)

🐔 Chickens can already eat Croptopia seeds, so no change needed there.
