Sydney got himself up to that bed without any plans for company, I think.. then Poppy decided she needed a warm snuggle.

Poppy remembers when she was a little kitten and first was here, Sydney adopted her as his baby sister and showed her the ropes.

They both make it clear they haven't forgotten their relationship. They still groom each other, cuddle up together, on occasion.. not all that often, but often enough to remind each other and me.
