Goat milk prepared for cats should be consumed within 6 hours, and within 4 hours in summer. If it exceeds this time, it must be thrown away, because the shelf life of brewed goat milk powder is very short. Goat milk powder will deteriorate over time, and cats who drink it will cause discomfort and symptoms such as vomiting and diarrhea. It is recommended that owners prepare goat milk powder for cats in small amounts and frequently to avoid waste.
