In Pet Empire, your pet warriors need to stay hydrated to stay in top fighting form. Water is essential for your pets to stay healthy and energized during their drilling sessions. With each supply of water, your pet can drill for up to 3 hours before needing another drink. Keep a close eye on your pet's water supply and make sure to replenish it regularly to maximize their training potential. With enough water and dedication, your pet warriors will be unstoppable on the battlefield.
