We adopted 2 cats and they are both very skiddish, so I wasn't sure they would like the self cleaning litter box, well they both hopped right in and no problem at all,  my husband and I are so glad that our cat's are not afraid of it. The Scoop free classic self cleaning litter box is easy to set up,  easy to clean,  and really quiet.  I would definitely recommend it to my friends and family.
