Make use of a harness
A cat harness is a piece of equipment used by cat parents to walk their cats; if you want to take your feline companion to the vet without using a carrier, you should consider using a harness instead.
A basket or a bed can be a good option if your cat is calm.
If your cat is calm, a basket or a bed can be a good option; if your cat is older and very gentle, you may be able to contain him in a basket or bed if you have one.However, this is only an option if you are confident in your cat's temperament; you don't want to jeopardize your cat's safety, as well as the safety of other people and animals in the waiting room, by allowing your cat to leap out and cause a commotion.
When using this strategy, exercise caution because even the most docile cats can become terrified in an unusual or frightening situation, such as a veterinarian's office.

Getting Your Cat Used to Traveling in a Car
If possible, start when you are young. If you want to take your cat to the vet without using a crate, you must first train him to be comfortable in the car without his crate.When you get a kitten, it's much easier to introduce him to the car than when you get an adult cat.
Gradually introduce your cat to the car.
Because a car can be a frightening environment for a cat, it is best to introduce him to the car in small groups at a time.
Keep your cat calm and provide him with treats and affection as he adjusts to his new surroundings by bringing him into the car when it is not in motion.Allow him to explore the car in small bursts for a couple of weeks to familiarize himself with his new surroundings.

Practice driving before going to the veterinarian.
Once your cat is comfortable in the car, you should start taking him along for the ride.
Precautions should be taken
Even the calmest cats can become agitated in the car if startled, so bags or baskets can be used to restrain a cat so that he does not interfere with your driving while you are on the road.Furthermore, a harness or strap can be used to restrain him. You don't want your cat crawling under your feet or beneath the brake/gas pedal while you're driving, as this could easily result in an automobile accident.
Prepare your cat to ride public transportation.
Before taking your cat to the vet, if you don't have access to a car, you'll need to get him used to using public transportation. You can practice by taking a short bus, train, or metro ride.You will likely be unable to transport your cat on public transportation, such as the metro, with only a harness or in a basket without a lid, as the vast majority of public transit alternatives in a city require that your cat be restrained in some form of kennel or bag.If you plan to use this technique to keep your cat secure while visiting the vet, you might want to take a cab or enlist the help of a friend.

Certain carriers are recommended by veterinarians for a reason: they provide several safety elements that are critical for your cat.
Transporters ensure that your cat does not wander around the vehicle, potentially causing an accident by interfering with your driving.
Cats are more likely to flee when they are scared, so if your cat escapes through the car door, he may be difficult to find.Veterinarian offices are frequently located in areas with a high concentration of automobiles, which may be hazardous to your cat's health.
If your cat is docile, don't assume that other animals will behave similarly; many canines are not friendly toward cats, and your cat is better off being contained within a carrier if a dog becomes violent.
Look for ways to make a carrier's job less stressful.
If you are primarily opposed to using a carrier due to stress concerns, there are steps you can take to make using a carrier less unpleasant for your feline companion.
