Sorry to be a party poo-per!
We use Golden White cat litter from Zooplus and it's been great for combating smells. I decided to investigate other brands of dry food, rather than the limited options at the supermarkets. I'd spotted that Sanabelle Adult with Poultry had good reviews and decided to order a couple of bags. We have two house cats - an Oriental and a Bengal/Oriental cross. The large enclosed cat litter tray is situated in our large kitchen extension and I can REALLY smell it, regardless of us cleaning it out.
