This cat/kitty litter can be composted just fine.  Mix well with other organic waste and dry carbon-rich material for best results.  This will work for both the clay and silica type kitty litters.
  
We recommend for safety that compost generated from any waste contaminated with faeces be used on ornamental plants rather than plants you will be eating.  
You can have a dedicated Subpod for use just for your pets :)
