Why harness a cat? Don't they hate it?

Depends on the cat! Some actually enjoy being accessories (before or after the fact), going places with you and being admired by passersby. The rest might still have to be prevented from fleeing if startled while already stressed - such as when they're handled by strangers at vets' offices or adoption events. I once saw airport security make a passenger remove a VERY nervous cat from its already-X-rayed crate while they disassembled and carefully examined every piece - and then somebody in the nearby arrival aisle tripped the "wrong-way" alarm, strobes and sirens and all. . .

Depends on the harness too! When I realized I had a foster-cat amenable to leashed walks, I tried several different harness types to see which she liked best. That would be the type I'd try out on new candidates. I discovered:
  1. Like me with scuba gear, they prefer minimal weight, bulk, stiffness, and hard lumps.
  2. They don't like having their heads pushed through a tight-fitting loop that bends back their ears, eyebrows, and whiskers on its way on or off. However, they don't seem to mind putting their heads into a bigger loop that clears all their various protuberances.
  3. They have no patience for prolonged fiddling to get the harness on and adjusted properly.
    • It shouldn't be easy to put the harness on inside-out or backwards, or get the straps twisted.
    • If there is a "wrong way" to put it on, the goof should be detectable well before the very last step.
    • Goofs should be fixable without taking the whole thing off and starting over.
    • Size adjustments should be quick, smooth, and not require much iteration.
Most commercial cat harnesses are just smaller dog harnesses. These produce mixed results, both in security and in wearer acceptance. I've observed
  • Most dogs usually take a Terminator-1 approach to escape, leveraging their musculo-skeletal strength, momentum and, well, doggedness. Therefore, they need every bit of that Mil-Spec material and hardware you find on dog harnesses.
  • By contrast, most cats (also ferrets, rabbits, rodents, otters and others) escape more like Terminator 2 They change shape, shift their centers all over the place, even seem to temporarily liquefy, vaporize, or fold through some eldritch parallel dimension. They don't need as much ruggedness, but they need a shape that will adhere to their contortions like white (or brown, red, black, or purple) on rice without blocking their breath or circulation.

Escape shouldn't be absolutely impossible, because "what if" they get the harness caught on something and can't summon human help? But it should either require emergency adrenaline or prolonged work on the cat's part; it should stay on unless it really needs to come off.

Harnessing a non-consenting cat can be very difficult. Kittens, on average, tend to be most open to new adventures. I've also had good luck with young "re-entry moms" who get fidgety and bored once they're spayed and the kids are growing up and moving out. Unfortunately, the "backpack-type" buckles and clasps on commercial harnesses can be too small for grownup helper-monkey fingers to operate easily and yet still too big and bumpy for kittens to wear. The parts for this harness are soft, flexible, and lightweight without being too fiddly.

Commercial cat harnesses retail for $10-30. Kittens outgrow them quickly, Some cats shred the outer surfaces. Adopters often ask if their new cat can keep the harness. I don't have the heart to say no or charge them extra (I do draw the line at letting them keep my iPad with the hiccup.com games for cats though). These harnesses can cost less than $2 each to make, and can be a kids' class project. The second one you make will probably take you less time than reading this page. And if a piece gets messed up, it's easy to replace it or re-use other pieces.

Props to (non-marshmallow) peeps:

  • Thanks very much to DoggieStylish, whose "Small Dog Harness out of Grosgrain Ribbon" Instructable pointed me in the direction I'd been looking for.
  • Models courtesy of Captivating Cats Rescue in San Jose, CA. LOLworthy Norah just got adopted - Yayyy! Unsettlingly clever MaReine (who TOOK OUR SIDE DOOR APART!!) and her intrepid sons Giacomo and AnDe have their "spades & newts," shots, chips and are ready to take over your world. . .

Step 1: Get Your Stuff Together

Clockwise spiraling in from top:
  1. Ribbon or braid, 0.5-1.5m long, 6-25mm wide, depending on size of cat -- should have some texture and body but not be too scratchy or stiff. Grosgrain or velvet ribbon, bias tape, hem tape and lightweight cotton twill braid seem to work pretty well. I avoid florist's ribbon with wire inside, in case kitties chew it. Satin ribbon is kind of slippery and flaccid for this design; if you've got some that's otherwise sublime, sew or fuse it to a grosgrain or velvet backing. This will be the strapping.
  2. Scissors to cut the strapping; Good Sewing Scissors (GSS) OK.
  3. Side Cutters (or Small Craft Knife e.g. X-Acto(TM)) to cut vinyl tubing. The GSS is the wrong tool for that part of the job and not worth risking the Stitcher's Holy Wrath.
  4. Bent Wire, 18-24ga., 3-4"/75-100mm long before bending, A bobby pin works in a pinch but is a bit harder to use. This will be the bodkin - a tool, not a permanent part of the harness, so you can use it over and over
  5. Hair Elastics (2) -- the continuous-ring knit-covered kind with no pokey metal or plastic clasp. Little-kid ones (~1"/25mm dia.) are best for cats under 5lb but a regular one (about 2x as big, as shown here) will also work. These come in all kinds of colors, patterns and textures to match or contrast with the strapping. These will be the sliders.
  6. Split Rings (2), 12-19mm, strong metal e.g. nickel or steel. AKA "keyrings for pixies." Both jewelry and fishing ones work. These will be the leash links (also handy for a tag, reflector, or jinglebell), so jump-rings are NOT a good substitute; they'd pull apart easily and expose sharp ends.
  7. Vinyl Tubing, 0.25"/6.4mm OD (or thereabouts) 1-2" long depending on size of cat. This will be the cord-stop. Readymade cord-stops for duffels and jackets will work, but these are more comfortable for the cat (as well as cheaper).
<p>Love your initial introduction and the pic, but I'm missing something. It was quite an exercise in concentration and I had to draw a couple of pictures to label the parts so I could understand. But if both the sliders are on the underside (breastbone) of the cat with the rings between them, then what is the purpose of the rings and how do you attach a lead? </p>
<p>thanks you gave me some ideas, thou i think this needs a lot of more work!</p>
<p>Having made this harness, I don't recommend it. It takes a while to put on and even longer to take off, which is a bad idea with cats. You end up with two loose bits of ribbon on the cat's back, which the cat can twist round and get at with her teeth. And most importantly, there's nowhere to attach a leash to! I ended up buying her a custom-made walking jacket, which is much sturdier, impossible to get out of, and is working beautifully for walks.</p>
<p>Thank you for sharing this cool Instructable! I loved your &quot;Why a cat harness&quot; explanation &amp; your witty sense of humor too! :D I have to admit, I was attracted to this project since &quot;no-sew&quot; was in the title and I'm not the most crafty with a sewing machine. (Give me a welder &amp; some metal though, &amp; I couldn't be happier.) Although, for this kind of project, I don't think my cats would be heavy metal fans, lol. I'm also not too good with the paracord knotting &amp; crocheting. Those are the only other styles of harnesses I've seen so far. This one actually seems doable for me! I have ASD &amp; ADHD &amp; about 7 months ago, my brother gave me a kitten that he rescued from a dumpster. (If I could get my hands on the jerk who did that.... Grrrr!) Turns out that this little furboy has a feline form of ADHD! (Didn't know that was possible, but the vet said it does happen) He's so fast, we named him &quot;Maserati&quot;, but call him &quot;Masi&quot; for short. He wants to go outside, but he gets SO distracted, just like me-haha, I'm afraid he'll get lost, injured or even killed. This is the purrfect solution &amp; by making it myself, I know it'll fit well &amp; be comfy. Can't wait to make it! Again, thank you so much! This is awesome! :)</p>
You like this quote kitty
the First cat says &quot;Holy crap get thing off of me. I'M GONA DIE!&quot;
I agree with you there.
hahaha love the expression :)
This is a nice idea!
Cool. My kittens are parkour enthusiasts too!
Oh that little kitty is adorable! The harness is awesome too :)
