It can be used for several years.
As a general rule, although it depends on your cat's preferences and how often they scratch, some customers have been able to use the Cat Cellar for two years without replacing any parts. It is also possible to use it for even longer by using replacement parts.
The Cat Cellar mini has only been on the market for a year, so there is no proven track record, but it is made from the same materials as the Cat Cellar, so we think it can be used for more than a year.
