Aumüller Silver Vine Cat Sticks

I bought this for my cats to help clean their teeth; unfortunately, this product is old and very hard, so I think it’s even dangerous to give to cats.

I gave each of my 4 cats a stick, under supervision... they absolutely loved it! After half an hour, I took the sticks away, since it was their mealtime. Two days later, I wanted to give them the sticks again. Not only their own sticks, but also the rest of the sticks (which were still in the original packaging) were all mouldy! 😭
