Enrichment does not need to fill every corner of a home. A stable perch, a covered resting spot, a scratching surface and a short interactive play session can give a cat useful choices through the day.
Offer variety and let your cat choose
Rotate a few safe toys instead of leaving everything out at once. Try a food puzzle only if your cat is comfortable using it, and supervise toys with strings or small parts. Keep food, water, litter and resting areas accessible without forcing cats to compete for the same spot.
Watch what your cat actually uses. A cardboard box may be more appealing than an expensive toy, and a shy cat may prefer a quiet retreat over a busy play area. Sudden changes in behavior, appetite or litter habits deserve a conversation with your veterinarian.
