I have been officially car-free for only a few months, but, in my mind, car-free for much longer than that (drove the car only from one parking spot to another so it didn't sit too long). The only obstacle I have come across is how to take my cats to the vet. I ride an old road bike and only have a quick-release rack for the back. I've googled bike pet-carriers and have yet to find anything worthwhile. What do you do? I took one of my cats on the bus, but would prefer not to do it again if I can avoid it. Any ideas?
