Military police were called to the house around 10 a.m. after getting a phone call about potential animal cruelty and/or neglect. Morales was taken into custody at Noon. A Fort Hood spokesman said the animals were dogs and that they would be okay.
Fort Hood officials said there is no indication her arrest was related to the death investigation of Gregory Morales.
Gregory's remains were discovered June 19 behind a Killeen neighborhood. He was last seen alive August 19.
The Army initially listed him as AWOL then as a deserter but his status was changed to active Wednesday. The change in status allows for him to have a burial with full military honors.
Fort Hood said his status was changed based on "trustworthy investigative updates" into his disappearance with investigators. Killeen police are the lead agency on the case.
The Army Criminal Investigation Division said they suspect foul play in Morales' death. They offered a reward of up to $25,000 to anyone with credible information about the circumstances surrounding his death.
