Patricia Schenck, 55, was charged with a felony last month in Clinton County District Court. A preliminary hearing to determine whether there's enough evidence for trial is planned for Thursday.
Schenck's lawyer Mick Grewal said negotiations with prosecutors were ongoing.
"I'm trying to do something that's beneficial for my client, as well as the animals," he said.
Schenck is suspended with pay from the College of Veterinary Medicine pending the case's outcome, university spokesman Kent Cassella said.
"In her role at the college, Schenck did not treat animals nor do the charges against her pertain to her work with the college," Cassella said.
Schenck, who in 2010 published a book titled "Home-Prepared Dog and Cat Diets, Second Edition," is listed as an assistant professor who specializes in endocrinology.
Officials said the animals were found Dec. 12 at the home north of Lansing in Olive Township, where Schenck lives with her elderly parents. The Clinton County Sheriff's Department went to the home after receiving a 911 call from someone who hung up.
Schenck was arraigned Dec. 20 and was released after posting bond. She has been ordered not to have any animals in her possession, records show.
Most of the animals were taken to local shelters for care, and Grewal said one dog was euthanized.
Schenck faces up to four years in prison if convicted.
