To help your cat feel safe ensure they have a comfortable, warm and easily accessible place to sleep and hide inside. This can be an igloo, cardboard box, even the top of a cupboard whatever your cat feels most comfortable in.
Ensure your cat is safely indoors before dark and all doors, windows and cat flaps are locked so that they cannot escape should they be startled.
Playing relaxing music or watching TV can also help to muffle the loud bangs, and having treats and fun toys to hand can certainly help provide a distraction from what is going on outside
Provide them with plenty of litter trays to use placed in different locations. This is especially important if your cat is used to toileting outdoors - we would suggest one per cat plus one extra and make sure you ‘practice’ ahead of the fireworks season.
If you have more than one cat, ensure you have separate feeding stations and water dishes as well as plenty of elevated hiding places for them to escape to.
