Using the PetSafe SlimCat Feeder is easy. First, open the feeder and fill it with either dry cat food or treats. You can adjust the size of the openings according to how challenging you want the feeding process to be for your cat. Then, give the feeder to your cat and watch as they play and work to get the food out. As for maintenance, you can place it on the top rack of your dishwasher for a thorough clean. Make sure to check the feeder regularly for any signs of wear and tear. When it comes to storage, keep it in a dry place. And always ensure the food you put in is fresh and suitable for your cat. Also, remember to supervise your cat during playtime with the feeder to prevent any potential issues.
