"I thought 'that's strange' because there aren't any dogs around us and it sounded like it was in a lot of pain," Ms Round said.
"My partner and I both got out of bed and ran outside and saw a husky dog with my cat in its mouth.
"It was throwing her from one end of the lawn to the next like a toy. I was in hysterics, screaming 'it's killing my cat, it's killing my cat'.
"Neighbours came and one of them held the husky down with their knee while my partner put our vacuum cleaner pole in its mouth."
Ms Round and her partner then rushed 9-year-old Sparkle to the vet but she was unable to be saved.
"Sparkle died of severe internal haemorrhaging. Basically, the husky bit into her stomach and crushed it."
Ms Round was given Sparkle by her grandfather as a kitten.
Feeling "in shock" and "distraught" about what happened, she posted on several social media pages last night offering $500 for information which would lead to identification of the husky and its owner.
She didn't want the dog to be destroyed but was adamant that it be secured more safely in future.
