I currently have a semi long haired cat and I'm getting two kittens in a few weeks, one long haired and one short haired. Pepsi currently goes outside and uses a patch of gravel/sand in the "field" (tiny patch of overgrown land it doesn't below to anyone) outside my house and refuses to use a tray unless he is desperate. We had to keep him in for a few weeks last year due to scratches from a rabbit that wouldn't heal. He finally used it after holding it in for 4 days . We've just been using asda smart price litter as he only usually gets kept in once or twice a year. It's clay based which I heard was unsafe for kittens and once it's been used once the whole thing needs emptied. Which is ok for a few days a year but not really practical once I get the kittens. So I'm hoping for a kitten safe, clumping, flushable litter that doesn't track all over the house with long haired kitties. I was looking at oko plus but heard that it tracks everywhere so not really an option. Oko plus is almost £10 for 10l from pets at home and asda's is £1.50 for the same amount, which would be better value?
