Provide puzzle feeders, hidden treat balls, tunnel gyms allowing independent play so they learn entertaining themselves while you’re occupied.
Enrichment
Initiate quality one-on-one play sessions before you get busy so they have an activity outlet preventing bored nagging for focus.
Schedule
Note body language precedes demands like staring, circling feet, tail up positioning so you can initiate pats before vocalizing starts.
Signals
Use compressed air, aluminum foil or upside down double sided tape to discourage countertop begging, unwanted chewing, scratching.
Deterrents
Give heavier praise/treats when entertaining themselves quietly to positively reinforce more independent calm conduct.
Positive
Try synthetic feline pheromone plug-ins that mimic nursing mother cats' chemistry signaling everything’s OK reducing separation stress.
Pheromones
Adopting a bonded second kitten or cat provides play company so they don’t fixate on you solely for stimulation.
