I purchased the litter-robot connect about a month ago and am absolutely in love!! Firstly, the customer service from Mary was some of the best I have received. She was so helpful with all the questions I had before purchasing and then during set-up and transition, and some trouble shooting I had. Mary always added extra advice and suggestions along the way to make the whole transition from litter trays to the robot stress free.
I have 2x British Shorthair kitties, one is an adult and 9kg, and the other still a kitten but already almost 5kg. I was initially a bit nervous they wouldn't like the smaller space, as I had the largest jumbo hooded ones you could buy, it was like a private sand pit to them, but thankfully they happily transitioned after a few nervous inspections and sniffs, after 2 weeks they were both more than happy with the new loo. One of the best things bout the robot is not having to bend down to scoop morning and night, I just wait for the robot to tell me to empty the tray and its done in a couple of minutes. There is absolutely no smell, and I just love it! I particularly love the nice Grey colour too. It looks very classy.
You won't be disappointed in buying a litter robot for your cats, it is truly an amazing product, and comes with some of the best customer service you could ever ask for.
