Brilliant, i just love these!
I buy the 3 pack for £12.99, 3 packs at at time to last me just over 2 months (and to save on the delivery charge) Excellent value as in supermarkets and pet stores the cheapest i have found it is £7.00 for 1 pack. One usually lasts a little over a week and they are so easy to use. You put it in a litter tray and just open it up. To change it you simply lift it out and put in a bin bag! Takes me less than 2 minutes now to empty and replace. Costs a little more than the regular catsan, but they do last longer and are SO easy to clean, there is a absorbant pad in the bottom for urine and the liner too. I use to have to scrub and disinfect my litter traywhenever i changed it but now i just wipe it with a antibac wipe as it stays clean. I would recomend the catsan smart packs to everyone, i refuse to use anything else now
