That poor kitty.
She's been through so much.
Sending chin scritches and gentle hugs her way.
that her paws heal soon.
If they wanted clumping litter, they should have at least used Swheat Scoop (swheat scoop is advertised safe for newly declawed cats) or Feline Pine scoop.
And a plastic under-bed storage box probably would have solved the litter pan issue.
(my sister uses those for her litter pans, I have to use high sided sterilites)
