I have a 12 week old kitten. We have started using the Catsan Smart Pack which is £7.00 for 2 smart packs. I have changed it after 1 week, it wasnt smelly at all. How often should I do it? It seems rather expensive if I do change it weekly, or is that about right?
If I am using regular Catsan, how often would you change that?
Thanks in advance.
