Nettles has a hobby, and that hobby is fetch. Specifically, fetch with her rings. She will bring them back. She will drop them at your feet. She will wait. This can continue indefinitely.
When she’s off the clock, Nettles follows her foster mom from room to room. She’s extremely social and wants to be involved in everything you do. She’ll lay on the piano while you practice. She’ll watch historical biographies with you and appears to have opinions about them.
She’s not a lap cat, but she doesn’t need to be. She’d rather be right next to you, supervising.
Nettles would prefer to be your only pet. She doesn’t care for other animals, which just means all of her considerable affection goes directly to you.
