I am starting to think about the long warm summer days

At weekends and in the evenings when I am home it would be nice to have the back door open but what do owners do with their indoor cats?

I wondered about putting her in a harness on a lead and securing to a post, or something like the kittywalk system but this would be one of the free standing ones, so I woud have to put her in and then take her out when I think she wants to come inside.

I emailed Kittywalk to ask about carriage from the US and although the system is quite expensive if it works then that's OK.

Does anyone have any experience of the Kittywalk products.
