My hound dog recently decided that chewing on the spout of her Lixit water bottle was a good idea. I thought perhaps giving her a different method for obtaining water would be a better idea, so I purchased the Lanca 2 No Spill Cup. It attached very easily to the door portion of her large plastic crate, no problem at all. Day 1: When I got home from work the cup was no longer attached to the door, and the no spill lip had been removed as well. Day 2: When I got home from work not only was the cup no longer attached to the door, and the spill lip removed, but she had chewed on both parts. Obviously this poses a choking hazard. So to those fur baby parents that have chewers, this may not be the best product for you. It can be removed from the crate door way too easily.
