It's always great to run into fellow cat folk. The Rocky Mountain Alley Cat Alliance has a booth at the CAACO conference. Cool t-shirts, plus an Alley Cat Allies book that I don't yet have. Good thing I brought extra cash...I like using the excuse that it's for a good cause!
Drat. I missed asking them about them before they packed up to leave. However, they are available from the Alley Cat Allies webpage.
