Renovation, HDB HIP works, fumigation, and a house move all look different on paper. From a cat's point of view they're the same event: their safe, predictable territory turns into a building site. Doors and gates get left open for workmen and materials, and a frightened cat bolts. Dust, drilling, and pest-control chemicals go on for hours, sometimes days.
It's not something a cat can opt out of the way a person can go to the office. We keep guests through renovations, HIP works, fumigation days, and house moves for exactly that reason: a private suite, away from the noise and the open front door, for as long as the works take.
