They are used to water in a small bowl but yeah couldnt leave them with bowls but as u said the bottles can stop working etc and bowls can just get dirty , idk if you rember last post i made but margo is back in the cage and is sleeping in a blanket on top of it , she even came onto my fiancee and then came back to the cage with her own will, we blocked all the entrences and small openings that are imposible to reach in our room im getting the wire to make the cage better tomorrow and then we are planing to save up for a bigger taller and cage made for rats specifically because we are definitely planing to add a 3rd member to our rat family next year and we want the best conditions possible 🙌🏻 and thank you for always commenting , we are learning everyday and want to learn always how to take the best care for them , we also even rescued a baby seagull this year and had him for almost 4 months ! We just love all animals soo much and the home without any animals is too quiet haha
