get a pet stroller!
Mine are loving the stroller so far. We haven't had many nice days yet to go for walks, but that should be changing soon. I was transplanting some of my tomato seedlings and looked over to see a cat in the stroller, waiting. I felt bad because I was rushing to finish before storms came as it was, and didn't have time for a walk today.
BTW, I carry pepper spray when walking my cats in harness...just in case. Haven't had to use it yet, thankfully, but it's there if I need it.
