I have 5 indoor cats, and currently use worlds best CL and 2 huge trays.
If I get a forever tray how long are the crystals expected to last, ie if they are supposed to last 1 month with 1 cat will I having to be changing the entire box twice a week?
How many cats can the SF cater for, ie would 2 be enough to cope with 5 cats, I will obviously only be getting 1 until I can ensure that they will all use it before getting a second.
what I am trying to do is ensure that it doesn't work out more expensive for me to run the SF rather than WBCL in normal litter trays as I do find that expensive but lasts a long time, but the thought of not having to scoop 4 - 5 times a day sounds like heaven, and just empty the tray at the end of the day
thanks
