Once you’ve figured out what’s changed in your home or your kitten, you can begin to solve the issue. This might be something really straightforward. Like making sure the litter tray is regularly cleaned or moving it back to where it once was. If you’re suddenly away from home more, your kitten might be lonely and suffering from separation anxiety. Plenty of fun toys or a visit from a friendly face during the day might help to pass the hours (and keep your home accident-free).
If a change has happened - like you’ve changed their litter tray or cat litter - you’ll need plenty of patience as they adjust to this. It can take up to 10 days to transition slowly to a new cat litter, for example. Some changes - like having friends or family visiting, or moving to a new home - might have a temporary impact on their litter tray use. In which case, give them time to get used to the recent changes.
If the litter tray accidents have started after medical stuff, like surgery or being on medication, see your vet to see if they’re related. The same goes if you notice a change in their personality, like they’ve become more fearful.
For some changes, you might have to revert back. Kittens have a great sense of smell and a new cleaner with a different smell might be off-putting to them or they might not be fans of their new food. Although if they’re on a new diet because of medical reasons, always talk to your vet before abandoning it.
