I decided to trial a new cat litter. It is wheat based. Made of wheat husks or something. I have one open cat litter tray, which I can't put anywhere where the dogs can't reach it. The dogs now just eat the litter as a snack!
Which is bloody ironic when I go out of my way to feed them a grain free diet!
This stuff is quite expensive, so I'm going to finish my stash (had to buy in bulk because you can only buy it online). But then I'm switching back to something that doesn't resemble cocaine for dogs!
