Shinya watched as Kaoru held the kitten, the image before him being one of endearment mixed with anxiety. Sure, cats landed on their feet, but Kaoru would likely go into cardiac arrest if the kitten squirmed a little too much and fell from his hands. The thought had him ready and prepared to step forward as the other man looked at him like that.
"They're not that hard to figure out, cats especially. They just need food, a little attention, and some interesting toys." He smiled a little, and when Kaoru shifted the kitten around in his hands, Shinya chuckled and stepped towards the pair, reaching out to carefully pick the kitten up out of Kaoru's hands.
This was definitely a bad idea. There was no turning away from this getting a kitten idea now that he was holding such a cute little thing in his hands. He was so engrossed in stroking the kitten's head with his finger that he barely heard the door opening--but the voice that called out soon after was hard to miss, especially that specific pet name that was used.
After glancing at the bathroom door, he turned towards Kaoru and raised a brow, thousands of questions in his eyes but none quite making it past his lips.
