Kaytee was formed in 1866 by William N. Knauf and Frank Tesch (K & T) as a feed mill which supplied seed to farmers. In 1920, the company became a national supplier of peas to be used for pigeon feed. It expanded into making feed for birds and other small animals, becoming the first commercial supplier of wild bird seed in 1955.
William Engler Sr., long-term employee and son-in-law of William N. Knauf, purchased the company in 1964 and renamed it Kaytee Products, Inc. His son, Bill Engler Jr., took over the company in 1982. Bill Engler Jr. was named the Small Business Person of the Year in 1993 by United States President Bill Clinton. As of 1993, Kaytee had 365 employees and annual sales of about $70 million. At that time, it also held about 1300 exotic bird species in an aviary in Chilton.
In April 2012, Kaytee recalled five lots of parrot handfeeding formula due to excessive vitamin D (which was causing kidney failure). This was acknowledged on the Kaytee website  as well as through emails with some customers. 
In February 2013, Kaytee recalled a number of treat mixes due to reports from their parsley supplier of salmonella contamination. No salmonela was found in the actual treat mixes, but to comply with FDA regulations they recalled all mixes containing that parsley.
