To clean her teeth
We recently spent seven hundred pounds at the vet as our cat had dental treatment with a couple of extractions, and our vet recommended this kibble to encourage our cat to crunch it up and clean her teeth. A good idea in theory but our greedy moggy swallowed them down whole anyway and they reappeared in the litter tray with a bit of blood. So we have gone back to mainly wet food and a bit of smaller sized kibble.
