Siska had bought down all the blankets and pillows he could find. He wanted Cato to be able to build a proper nest, it had seemed important to the boy. So he put them all on the bed and went into the shower. Only stopping long enough to pull Cato into his arms on the way there, and give him a long kiss. He couldn't get those tones out of his head and Siska did a deep dive among his memories as he stood in the shower, cleaning off today's mishap.
He found it in a box he'd stashed away, labeled private, secret, dreams. The first time he told Dius he loved him.
Siska came out of the shower a few minutes later, got into the soft clothes Cato had put out for him. Face deep in thought, he padded on soft feet out to see what the boy had built.
Siska had more blankets and pillows than Cato would have thought and at some point, he promised himself, he'd go see what other neat things were in the attic. But not now. Now, he was busy arranging said pillows and blankets.
He fluffed the pillows to make them softer and made sure that only the softest blankets were near the center of the nest where they would lay. Cato purred to himself as he worked, making everything perfect and comfortable and just right. He'd never made a nest to share before, not in the same context. He'd made them with friends and family, little places to curl up and nap or just snuggle and talk.
This nest was different though. It was to show Siska that he loved him.
