Using this KONG Salmon Mousse is super easy. First, grab your Kitty KONG, KONG Licks pad, or other treat - dispensing toys. Then, use the mess - free nozzle to squeeze the mousse into the toy. If you're using the Kitty KONG, give it a little squirt at the openings to keep the stuffing in. Your cat will be drawn to the irresistible salmon flavor and start playing right away. After opening, always remember to put it in the fridge to keep it fresh. There's no special maintenance needed for the mousse itself, but make sure to clean the toys regularly to keep them in good condition for your cat to enjoy more playtime with this delicious treat.
