There are few cats I've met that tolerate being ignored, they just escalate their activities until there's a choice between 'give attention to cat' and 'buy new carpet / furniture / bedding / clothes'.
(coming from me though, who can't ignore the big, scruffy -to put it mildly - neighbourhood stray tom cat that comes to visit a few days per year for the last six or seven years)
