Kids often give their grandmothers trouble for taking in strays like a crazy old cat lady, but this act of kindness really shows that she's a good person so they generally don't dissuade her from continuing to collect cats.
But when Eric Hertlein went to visit his grandma at her home in Kansas he saw something that caused him to be concerned about her cat collecting and her eyesight- because one of the strays she was taking care of wasn't a cat at all.
His grandma thought she'd been taking care of three stray cats, but one of them was an opossum imposter pretending to be a cat so he could live the sweet life indoors:
“She reassured me it was one of her cats,” he told The Dodo. “I told her it wasn’t what she thought it was.” The sweet woman even named him Tete, and though she was shocked to realize the truth, she didn’t mind too much at all. “Well, he hasn’t bothered me yet, so I’m OK with him being here!” she reportedly exclaimed.
