For an “About Me” section as the seller/owner, I’d make it more appropriate for someone responsibly selling their kitten:
I’m a private cat owner, not a commercial breeder. The kittens were born and raised in our family home with their mum and have been cared for with lots of attention from birth. They are used to people, everyday household activity and being handled.
I want each kitten to go to a responsible and loving permanent home, so I’m happy to answer questions, provide additional photos or videos, and arrange a viewing before purchase. Their welfare and finding the right new owners are very important to me.
