So we've had single cat strollers in the past for our cats but it was always a hassle trying to find time when both my husband and I could push both the cats at the same time. We bought this stroller a couple months ago and put it together immediately. It was fairly simple to set up, Just make sure you don't click the wheels on upside down like I did. It was very hard to get the wheel off after clicking it on upside down... But once we were up and running, It's been nothing but fun! Our two male Ragdoll cats are absolutely in love with their stroller rides. They practically demand it every morning now. They know as soon as I am done with my morning coffee that they can start meowing and walk towards the back door to their stroller. It's pretty much my new exercise routine!! Which is also a plus. I push them up and down the hills around our neighborhood, and they are just entranced by all the birds, morning joggers and little dogs they get to see. We simply couldn't live without a good stroller and this is definitely a good purchase if you have more than one cat. If your cats are small you could definitely fit more than one cat into each side. My cats are quite large and one is fat, so for them it just fits the two nicely with lots of room to turn around and look out of the different mesh cut outs. They love being able to look out the front and also the back. They get a complete 360 view, so they don't miss a thing. Cat mom and cat approved!
