Depends on the size of the cat, I've actually never seen a fox board, but would guess it to be the best fit. Only fox I ever put up, I put on a cat stretcher. I've got some jumbo cat boards that I do the little coyotes we have in this country on, but they are too big for 90% of our cats, so I'm assuming even your small coyote board will be too big for most cats. No wire. An otter board would work for small/medium cats except most otter boards have a very short, rounded head, and I prefer a narrower, more pointed head for cats. If you don't mind losing an otter board you can take one and trim the head down to make a cat stretcher.

If you're cat is too dry to turn easily when you take it off the stretcher, take a towel and soak it in hot water, thoroughly wring the water out and wrap the cat in the warm damp towel. In about five minutes it will turn easily. This is actually the way I do most of my cats, I put them on the stretcher and let them dry overnight, when I get up in the morning I take the first one off the stretcher, wrap in a towel and go on to the next, by the time I have the third one off the stretcher and wrapped in a towel the first one is ready to turn. No hassle or worries about ripping an overdry hide, and no worries about spoilage from stretching a green hide fur out. Much less hassle than the no-turn method in my opinion.

You can get a nice adjustable wooden stretcher for about $20 or so, Get at least one.
Makes all the diff if you sell your cats.
We used coyotes stretchers for years, our bobcats must be big because they fill them up. Bobcat boards have a little different shaped nose and taper, makes them look better.
We've talked at length with fur buyers, put them up right for the most money.

Wytex our cats aint your cats. Look at the picture I posted. Like I said even the local buyers dont use wood.

If your only catching a few, if they are not from CA NV OR WA ID UT WY NM or AZ the expense of wood wont pencil. You cant make silk from a pigs ear.

Cats like this don't live in IA
