Information Wanted!! Harness / stroller cats!

Hello, This ad might be a little weird. I am looking for fellow cat people who might be able to talk to me about harness training cats, and the pros and cons of having a pet stroller for day trips and etc. I do currently have a catio, but due to my new lease agreement I may have to sell it in the very near future, and I do not want to lock my cats indoors again. So if somebody who sees this also walks their kitties, or takes them out in strollers, please let me know! I would love any and all information regarding this life change! Thank you very much for your time.
