Animation is a very creative field, let us understand two things
If you want to become animator based on your creative skills like drawing etc. degree hardly matters, there good institues like Apeejay, Arena, Maac etc. you can join any of them but remember one very important before joining any center just check about faculty from senior students.
If you want to be part of senior management in any big company, Degree level course will help you because it will cover all the aspect about the technology which helps in taking decision about different types of multimedia projects.
One more thing if you have not done graduation than always go for a degree course because graduation degree is a must in most companies.
