FAQ

Popular questions

All questions
How long do alpacas live?
Alpacas typically live 15 to 20 years, and well-cared-for individuals can reach 25 or more. More
Do alpacas spit?
Yes, but mostly at each other — over food, space or unwanted mating attempts. Well-handled alpacas rarely spit at people. More
Can an alpaca live alone?
No. Alpacas are herd animals and become severely stressed alone. Keep at least two, and ideally three or more. More
How much land do alpacas need?
A common guideline is 5-10 alpacas per acre of good pasture, depending on rainfall and grass growth. With hay feeding, small herds can live on less. More
What do alpacas eat?
Mainly grass and grass hay, plus a camelid mineral or small amount of balanced pellet. Treats such as carrots should be small and occasional. More
How much does an alpaca cost?
Pet-quality geldings often sell for about $250-$1,500 each, while registered breeding females and top herdsires can cost several thousand dollars or more. More
