Day 64

Today Mimi jumped to the building in construction next door. Recently they build scaffolding and now it is accessible to the cats in a short leap from my clothes line. The waiter from the restaurant in the basement, that alerted us, was kind enough to go inside the building, catch her and hand her to me over the balcony.
No big scare: she has folen out of balconies three times, and got in complicated situations twice (once she got locked in a garden shed). We are getting used to it.

Ziggy digging on the bowl with a hole and a paper roll.

Ziggy is meowing a lot when it comes time to do #2. They both pee on the yellow bowl without problems but when it comes to poop it is a difficult for him to do it.   
I was reading a forum from one of the commercial kits, Litter Kwitter, and most people complain about that: cats pee on the apparatus but have trouble pooping – they prefer carpets and sometimes even beds… I would like to know the percentage of success of this commercial kits.
 

Ziggy, always digging, under the sceptical look of Mimi.
