I've visited some big department stores and got understood that all modern lavatory pans that are for sale there don't meet one very important requirement. The point is about our kitty and dog pets and the hygiene. Pets of most of us use lavatory pans equally and for the same purposes as we do! So I don't understand why the latest models of pens has no a usual forepart in the construction that is so necessary and useful for our kitties and dogs??? So I wish the pan producers take this into consideration and make our pets' life more comfortable!
