Awww, poor thing, it's going to die a virgin and no babies.
To be honest this sounds like my poor first kitty. My first kittybox I ever bought was from a cart. Then in a couple days I started getting messages in chat it was hungry. Thing is I couldn't remember where I opened the box. It is probable I opened it at the cart. Now there is a link under the complaints to it's location. I can't remember then if there was a link then. MIght hae been but I was pretty clueless years ago (and Winter -- if you comment on that clueless comment, I have a frying pan ready to swing!). It got to complaining over 100% hungry. It drove me just about nuts since I couldn't find it. Then I got a message from kc along the lines of you didn't feed your cat so it went to kitty heaven. Still didn't know what that meant but the complaints stopped.
Then years later I got an Advent cat at the KC store (which sold kibble and other cats so I found out it had to eat and could breed). I remember that cat and went searching through my inventory. Sure enough KC had returned it. I popped her out and poor thing was sick. Her health was -20211%! She was like over 1000 days old so she'd been in inventory for 3 years. (I can't help thinking of all the collectible kitties I missed in those years) I nursed her back to health and then permapetted her. She never had a baby, obviously.
I can't help wondering if that owner was like I was.

looking at this picture --- I think Lucy must have been live when I bought her -- look at her name! I didn't even know she was live! I thought she was a boxed kitten when I got her. Facepalms.
