Since we have both baby and cat, I have found that the refill cartridges for the Angelcare nappy bucket identical. Also comes both from the same factory in France.
Difference: The diaper pail refill cartridges are not only a whole corner cheaper, no that are also more productive.
Little Locker cassette: 95g Angelcare: 115g
According to my calculations are about 20% more! Have fun saving :)
