It's A Cat's Life by The Art File - 1000 Piece Jigsaw Puzzle (Gibsons)

Dozens of cats going about their business across a teal-green background — sleeping on bookshelves, peering through a window, sitting in plant pots, and generally ignoring each other. Every breed and colour seems to be represented, from sleek black cats to tabby stripes to the odd ginger sprawled across a rug. The Art File's illustration style keeps each cat distinct and full of character without tipping into sentimentality.

It's the kind of busy, all-over design that rewards a methodical approach — sorting by colour is less useful here than sorting by cat pose or the small props scattered between them. The teal background is consistent throughout, which keeps the piece count feeling like an honest 1000.
