Pet supermarket .co .uk (pet-supermarket.co.uk) is an excellent company. Delivery was a little slow but I was constantly informed and everything arrived as expeted. Prices are generaly on the afforable side so I will shop more with them for sure! The clamping litter I bought is great and my cat loves it. My cat NEVER ever wanted to use a litter box (but had a very bad experience with litter box with previous owner, before we rescued her) She waited out the storm if needed instead of using a litter box, just so she can go outside to do her business. And one day she decided: you know what, I am going to be comfortable and go for it. And since she never looked back, if rainly outside or under the weather or threatening winds? She chooses this organic clamping litter. Thank you to Pet Supermarket.
