This 500ml Tritan bottle, featuring a cat theme, from iDrink (reference ID2121H), is a reusable bottle made of transparent copolyester. Tritan is a BPA-free, transparent, and virtually unbreakable copolyester that does not retain odors or stains and is resistant to both heat and cold, making it dishwasher safe. The cat theme is one of the most classic and recognizable pet motifs in this range. It's a preferred option for cat lovers who prefer a more traditional theme than the more exotic animals in the same collection.
