We got this backpack for Harley late last Fall. (I'm pretty sure it's the "medium" one of these, but I don't remember where we got it.) It was really too cold to take Harley outside in it, but we got him accustomed to the space by hiding snacks inside, and encouraging him to climb around on it and in it. Once it got warm out, we put him inside while we were gardening, or otherwise puttering around outside the building. This condominium complex is pretty quiet, but there are still a couple of dogs and kids around, so the backpack gave him more privacy than his outside cage (picture pops).

It's only been pretty recently that we started taking him for walks in it. Because, you know, we're lazy slugs. By coincidence, we ran into a friend while we were on our second outing — she thought it was the cutest thing she'd ever seen! But the backpack isn't quite perfect. First, the last time we took him out he seemed to get a little overheated, so that's something we'll have to watch out for on a hot day.

The biggest problem, though, is that the lowest perch attachment is slightly high for dainty Harley, and the perch that came with it is a little too big in diameter. So if he falls off, he can't climb up again. It's easy enough to make new, thinner perches, but so far Harley has insisted on perching awkwardly on the dishes instead — I'm guessing because they're higher than the perch, and he just feels safer being higher up.

Next time I might just remove the dishes, since we're not going out long enough for him to need snacks or beverages. I'm also thinking of making some sort of ladder, or platform, instead of a perch, so he'll be able to hang on more easily. It is a moving backpack, after all.
