Is it hard to catch horses on horseisle?

Horses are not at all difficult to catch in Horse Isle They are found on every isle except Cloud Isle and in towns. If you happen to stumble upon a wild horse, an icon will appear in the upper right screen of your window, stating, "Horses Here: Wild Horse." To capture a horse, just use the lasso to try and get it around horse's neck. Don't worry if you fail the first time -- you can always try again by finding the horse, which only moves a couple of steps away from where you originally found it. Don't give up or get frustrated you'll catch it! Aim a few steps ahead of the horse so it can be in position of the circular part of the lasso to get it around it's neck.

If it says for example "You are in the town of Treeton on Horse Isle" then you won't find a horse. But if you take a few steps outside of Treeton and it says "You are on Horse Isle" you can find a horse! Once I found a horse a step outside (to the west near the rocks) of Wington on Bird Isle. Basically, just walk around until one pops up in the right-hand window, then click capture, then it's up to you whether you catch it, as it's sometimes hard to get the lasso on if you PC has a lag.
