Using your M - Pets Flaska water bottle is a breeze. First, use the wire attachment to secure the bottle to your pet's cage. Fill it up with fresh water every day to keep your pet hydrated. You can easily see how much water is left thanks to the clear milliliter measurements on the side. When it comes to cleaning, every now and then, take some lukewarm water and add a bit of soap. Wash the bottle well, then rinse it thoroughly before refilling. Remember, the price you pay is for one water bottle, and you can choose from four different sizes depending on your pet's needs. Enjoy the colorful addition to your pet's home with these assorted - colored bottles.
