A harness can give a cat who already enjoys it a little more supervised time outside, but it is not a good fit for every cat. Cats Protection says many cats find being restrained on a lead stressful, so I would not buy one on the assumption that any cat can be trained to enjoy walks. If yours is relaxed in a harness, the two options below offer different fits: a light strap design or a more covered vest.
Quick answer: The PetSafe Come With Me Kitty Harness and Bungee Leash (Ad) is the one to compare first if you want a lightweight harness and lead together. The rabbitgoo Cat Harness and Lead Set (Ad) is the vest-style alternative, with mesh coverage and reflective details. Neither is escape-proof, and the right size matters more than the style name.
I checked the current Amazon UK listings and manufacturer fitting information. I have not tested these harnesses on cats, so this is a comparison of the listed design and sizing, not a hands-on review. Prices, colours and stock can change; the buttons open the current listing.
Best cat harnesses and leads in the UK: quick comparison
| Harness | Best suited to | What stands out | Worth knowing |
|---|---|---|---|
| PetSafe Come With Me Kitty (Ad) | A cat comfortable with a light strap-style harness | Adjustable harness with a matching bungee lead | Less body coverage than a vest; measure the chest girth and follow the fitting guide. |
| rabbitgoo Cat Harness and Lead Set (Ad) | An owner looking for a vest-style fit | Mesh vest, reflective details and a 1.5 m lead on the checked listing | The listing has size and colour variations; check the measurements for the one selected. |
1. PetSafe Come With Me Kitty: lightweight harness and lead set
Best for: a cat who is already comfortable with a harness and an owner who wants a simple strap design with the lead included.
This PetSafe set is a practical first one to compare because it is adjustable and comes with a bungee lead. PetSafe says the harness is designed to rest around the shoulders rather than put pressure on the throat. The brand’s fitting guide shows how to position the chest slide and adjust the girth strap, which is useful because a harness that looks secure in a product photo can still fit badly on an individual cat.
For the medium option on the Amazon listing, the stated chest girth is 10.5–14 inches. Measure around the rib cage just behind the front legs, then check the listing’s size chart before choosing. The size ranges overlap, so do not assume the middle size is right just because your cat is an average weight.
The catch: this is a light strap-style design, not a padded vest. It may suit a cat who dislikes more material around their body, but it gives less coverage and is not a guarantee against backing out. PetSafe also says to remove it when it is not being used.
2. rabbitgoo Cat Harness and Lead Set: vest-style coverage
Best for: someone comparing a vest-style harness rather than narrow straps, provided their cat is happy wearing the extra material.
The checked green listing combines a mesh vest with reflective strips and a 1.5 m lead. Its product details list a neck measurement of 29–35 cm and a chest measurement of 46–51 cm for the selected size. Those are the figures to compare with your cat, not a general promise that the harness fits every adult cat. Other sizes and colours appear on the same listing, so double-check the selected variation before ordering.
A vest can feel more substantial than the PetSafe straps and may be the style you want to compare if you prefer more material around the chest. That does not make it escape-proof. Check that the harness sits correctly, that your cat can move comfortably, and that the lead attachment and fastenings are secure before you go outside.
The catch: some cats do not like the feeling of a vest or having it put on. If yours tries to wriggle away, freezes or seems distressed, take it off and stop. A different product is not always the answer; your cat may simply prefer not to wear a harness.
How to choose the right cat harness
Measure your cat, then use the size chart
Use a soft tape measure and follow the measurements requested by that particular brand. For the PetSafe harness, that means measuring the chest girth behind the front legs and around the rib cage. For the rabbitgoo listing, compare both neck and chest measurements with the selected size. Do not choose by weight, breed or the letter on the label alone.
Decide between straps and a vest by comfort, not appearance
A strap harness uses less material; a vest covers more of the body. Neither style is automatically safer for every cat. Your cat needs to be able to move comfortably, and you need to be able to fit and check it properly. If it rubs, twists, slips or makes your cat tense, do not take them outside in it.
Check what is included
Both products above are sold as harness-and-lead sets, but check the exact listing and selected variation before ordering. Lead length, colour and sizing can differ across versions. You do not need a long lead for a first try in a secure, familiar space; keeping it slack and letting the cat choose where to go is more sensible than pulling them along.
Getting a cat used to a harness
Do not put a new harness on and head straight outside. Leave it near your cat first, then try a brief indoor session with a treat or part of their normal food. Build up slowly only if they remain relaxed. Cats Protection advises introducing a harness gradually, waiting until a cat is comfortable indoors, and watching for signs of stress. If your cat seems unhappy, remove it and stop rather than trying to push through.
If your cat does settle into it, keep the first outdoor try close to home, somewhere quiet and familiar. Attach the lead to the harness, never a collar, keep it slack and let your cat set the pace. A harness does not remove the risk of a cat bolting or getting frightened, so make sure their microchip details are up to date before considering outdoor use.
For more detailed advice, read Cats Protection’s guidance on harnesses and leads and PetSafe’s fitting instructions.
Should you buy a cat harness?
Only if your cat is comfortable with one. A harness can be useful for a cat who already tolerates it, but it is not a must-have and it will not turn every cat into a walking companion. Cats Protection notes that many cats find lead walking stressful. If your cat would rather stay in, indoor play, a secure garden or a catio may be a better fit.
Which cat harness would I choose?
If your cat is relaxed wearing a harness and you want a lightweight strap style, compare the PetSafe Come With Me Kitty first. If you prefer a vest and your cat accepts more material around their body, compare the rabbitgoo harness and lead set. In either case, take the measurements before opening the Amazon listing and confirm the exact size and colour selected. If your cat dislikes the harness, the best choice may be not to use one.

Cat harness FAQs
Are cat harnesses safe?
They can be used for supervised outdoor access when a cat is comfortable wearing one and it fits correctly, but they are not risk-free. Cats can become frightened or get out of a harness. Introduce it slowly, watch your cat closely and do not attach a lead to a collar.
Can a cat escape from a harness?
Yes. A cat may back out of or wriggle free from a harness, particularly if it is loose, the wrong shape or not fitted correctly. Product descriptions that use phrases such as “escape proof” should not be treated as a guarantee.
Should kittens wear a harness?
Only use a harness sized for the kitten and introduce it gradually indoors. Kittens grow quickly, so check the fit often and follow the product’s minimum measurements. Do not take a kitten outside just because a harness is available.
