In 1961, the company was purchased by Jim Scott, a professional in animal nutrition, and moved to Lowell, Massachusetts.

In the 1990s, Jim Scott Jr., then CEO of the company, worked with a team of animal nutrition experts to develop the Wellness brand dog and cat foods, which went on the market in 1999 and 2000, respectively.

WellPet was purchased by Clearlake Capital Group L.P. in November 2020, and later renamed the Wellness Pet Company.

[2] The company also continues to make Old Mother Hubbard branded products, including dog biscuits[3] and other treats.

In August 2008 Wellness/Old Mother Hubbard was sold to Berwind [12] for $400 Million, generating a 7x profit on Catterton's initial investment.

[25] Its Whimzees brand is produced at its manufacturing campus in Veendam, The Netherlands,[26] which also received a AA rating.

[27][28] This product line was developed to meet the needs of pet-owners who are interested in providing their pets with versatile and fresh food.
