Make sure your cat has some shaded, cool spots to lie down in.
Place ice water in glasses and bowls around the house— cats are notorious for drinking out of any water container they can find.
Stroking your cat with a damp cloth is a great way to keep them cool (if they will allow it)— the best places to attend to are their paws, bellies and the outside of their ears. Brush your cat regularly— matted fur works as insulation, and will mean your cat can overheat more easily. If you have a long-haired cat and decide to shave them, leave at least a full inch of fur to help prevent sunburn.
Relocate your small animal to a cooler part of your home. Place ice cubes wrapped in a tea towel, a small frozen icepack, or a wet tea towel in their enclosure for them to lean against.
Small animals need to stay well hydrated, so fruit and vegetables high in water content, such as celery and apples, are a great and delicious way to help them avoid dehydration. Be careful to make sure the vegetables you feed to your small animal are appropriate for their dietary needs.
Half-fill a shallow children’s pool for your dog to bathe in— just make sure they can get in and out easily.
Put ice cubes in an indoor bowl and freeze a big block of ice for their outdoor bowl. Doggie ice blocks are also a great way to keep them hydrated— just freeze your dog’s favourite treat in water, inside a Kong, or an ice-cream container.
You can find cooling mats at most pet stores— these can be used as crate liners or as beds, and can be helpful for other animals too.
