PHOENIX -- In the past three months, Phoenix pet owner Kristi Perteet says she's had a dog and two cats shot with a pellet gun, and a third cat kicked so badly it had to be put down.Phoenix police are now investigating the possible cases of animal abuse.Perteet says the first shooting happened in July. Her 9-year-old cat, Jet, was shot in her front yard with a pellet gun. Jet was taken to the veterinarian and survived.The following month, another one of Perteet's cats reportedly leapt through her window trying to escape an attack."I had a cat that was kicked so hard that it broke its leg, and its pelvis bone went into its spinal cord," Perteet says. "We had to put her down; there was no saving her."In September, someone shot her dog, Ginger, in the face and neck with a pellet gun while she was in the backyard. Ginger survived the incident.Several days ago, Perteet had another cat shot and killed in her front yard."I heard the shot," Perteet says. "I got up and looked, and I didn’t see anybody."After the most recent shooting, a Phoenix Police Department spokesperson confirmed a detective has been assigned to the case.Perteet says she suspects someone in the neighborhood is behind all four incidents. She hopes whoever is responsible is caught before another one of the neighborhood pets is hurt or killed."I hope it makes them feel like a big person to hurt something so innocent," Perteet says.
