I know it’s frustrating when your cat doesn't show interest in the toys or items you've provided for them. Cats can be selective in their preferences, and their interests may change over time. Every cat is an individual with unique tastes. What works for one cat may not work for another. It may take some trial and error to find the toys and items that capture your cat's interest and keep them entertained.
Cats may take time to warm up to new items. Give them space and time to investigate and adjust to the new additions to their environment.
If your cat consistently ignores or avoids the items you've provided, consider consulting with a veterinarian to rule out any underlying health issues and to get tailored advice based on your cat's specific preferences and needs.
