Sorry but the first post on this question didn't work.
I am going to buy some more snares and was surprised that R.P, Outdoors says that 3/32' wire is what they recommend for Cats.
And 3/32' washer lock snares are even cheaper than 5/64"'s.
I remember catching a Coyote by the hind foot in a 3/32' snare years ago.
He went all the way through the snare and was caught by one hind foot.
So The 3/32" snares are good snares, I would expect that 5/64" would be better for as slinky of a critter as a Cat. A 3/32" snare is used for a Hog!
If it is strong enough for a Hog, isn't it just possible that a 5/64" snare would be better for Cat, the snare being lighter and less noicable to a critter as sensitive as a Cat?
