The outdoor-indoor cat thread got me thinking, as this is a subject I may have to deal with sometime soon. There is a chance that I may be moving away within the next few months, to somewhere cat-friendly, with a garden. As far as I know, Tiny and Simba have always been indoor cats, and for the most part, they seem happy with this, although I often think Tiny has too much energy to be kept indoors. Simba, being in the region of 10-11 years old to Tiny's 4-5, is noticeably more sedate and seems increasingly cheesed off with Tiny's boisterous wrestling games. Sometimes, after a particularly energetic match, Simba resembles one of Tiny's toys, soaking wet with Tiny's saliva and looking forlorn. Would it be possible or advisable to safely introduce Tiny to the outdoor world, after all this time? Ideally, I'd like a little rockery for Simba to potter about it on summer days, but I don't think Simba would love the opportunities for exercise as much as Tiny. What do you think?
