It is highly unlikely. The only possible way to get a horse is if someone else releases one. That is also highly unlikely because no one has horses on Welcome Isle. The only way to get a horse on Welcome Isle is if someone else comes on a Pegasus to Welcome Isle and lets one loose because once you leave Welcome Isle you can never come back.
Horses can be caught on any isle on horse isle, except;
After, you leave it, you can never go back
EDIT: Actually you can go back, if you have 100% quest points and have rented a pegasus or unicorn

Just look on isles without big towns that have arenas. (Savanna isle is a hot spot)
On Snow isle, Bashkir Curly's and other snow horses are found. As for items, mainly snowballs, and, if you are on Christmas isle, you will also find candy canes. A way to find out if a horse can be found in snow, is to look it up in the library. Most horses say where they are found on horseisle.
Desert and jungle isle are quite good.
Anywhere except towns and Cloud Isle . If your lucky, you'll find a wild horse in a house!!!
Horses can be found in every terrain outside of towns and not on Cloud isle.
Well there are a lot of answers but I think the best place would be Dry Isle's, Sunny Glade Isle And Prairie Isle are best spots if you look hard.
yes, you can find horses on every isle except for cloud isle.
let me guess horseisle? its Jungle isle
Cloud isle Christmas isle, where Santa is :)
hoof isle :)
you can ONLY find llamas on junle isle ( inless some relesse it on another isle )
On Horse Isle on the pathway you use when walking to Hoof Isle
To get a zebra you pretty much do the same thing you would to get other horses on horse isle. You can catch them, You can buy them off other players, you can trade other horses for them, ect.
