What to put under a parked cat on trailer?

I have a cat outside the house on a trailer. I can not grow grass under the cat and it just dirt, when it rains, the spash of mud on the trailer and hull bottons is too much to stomach.
Any low cost ideas of what works good to put under the trailer.
One person suggested nitpack (crushed stone stuff). Any other ideas?
Thanks

move the trailer occasionally?

I have crushed granite under mine.

Pour a concrete pad, approx 3 yards of concrete. A little work and approx $200. 3 yrd of concrete is approx 240 sq feet 4 inches thick. If it is next to a garage or next to the house it can be made to look like it belongs

Artificial turf!

Chop up your favorite monohull into 1" squares. spread evenly to a depth of 2"

Thats a good one!

sail it more often, let the grass grow

pavers?

tarp?

mulch?

shade loving ground cover?

Put it in a storage unit. I sailed mine for three years and got exactly what I paid for it when I sold it. Looked brand new.

Did you include 3 years of storage fee in your asking price?

How much was your storage fee to store a cat?

How about Cat litter, or A CatBox??
Sorry Man, Couldn't resist , , , Just pour a concrete pad, not that big a deal

Don't forget to get a building permit.

Just get some concrete garden tiles from craiglist and put them on the lawn. No pouring required.
That's what I'd do.

Put it in the garage and tell the wife sorry but the boat is an indoor/outdoor cat.
