My 11-year old male cat has for the past year started to always meow and hide after eating dinner. He gets 5 meals per day, 2 dry, 3 wet. After his fourth meal, which is wet, he walks away while meowing weirdly and loudly, often hiding, and then grooming himself a bit. Normally he's pretty social and wants cuddles after having eaten, but not after dinner. See video for example. Usually he hides under the kitchen table, but here he decided to sit by the window instead.

What might be causing this behavior? What is he trying to communicate?
