As others have said keep an eye on things. There a plenty of "stories" and real incidents that are supported with photos. "Boa eats royal" photos are on the net and easy to find. In the boa eating ball photos the snake doing the eating (boa) regurgitated early, but didn't survive. The royal was already breaking down from digestive acids and enzymes.

When they do regurgitate, its a somewhat stressful and energy consuming process.

I would skip a feedings for a bit, as snakes easily go without food for long periods. Then feed a smaller meal for the next go round. Make sure that meal is totally digested and eliminated before feeding again.

Some of this advice is cautious and is taken from BCC care practices as they are know to have issues when husbandry is not provided properly and meals are too large and frequent.There are cases where a regurgitation can set up a cycle of issues and lead to a pattern of further regurgitation issues. Again, this more applies to boas and more specifically Suri and Guyana area BCC's but under these circumstances I'll pass it along.

Play it safe if the animal survives this and slowly work back to normal.
