Cat NZ Green Lipped Mussel Oil

We have used this product twice before and our cats loved it. This time they won't touch it. Have the ingredients changed in any way?

My cat loves the Green Lipped Mussel Oil. It helps his hip pain. Thank you! This is a great product. The delivery service is also fast, from ordering to arrival at home.

This is the third bottle I have ordered. My cats are loving it ans they have thick and beautiful fur
