1. Love the crate. Including a crate into your cats normal routine as a snuggly safe space can really help when you need to take your cat somewhere. If this is not something you have already established, have the crate out at least 2 days before the vet visit
2. Cover the crate. Keeping the crate covered with a towel and using a calming spray on it will make the space feel even safer for your cat. Remember to keep the cat inside the crate during the journey and in the waiting room, until you are with the vet
3. Give them a smooth journey. Be sure not to bump and wobble the crate whilst transporting your cat and keep it up high when in the practice. Putting it on the floor often seems like a sensible place but it could leave it exposed to other animals especially dogs who may want to sniff it in the waiting room.
