"This is a despicable act that inflicted serious pain and suffering on two innocent cats. It's important that those responsible for this cruelty are held accountable."
This is the second time in a week that the SPCA Auckland has asked the public for help over an animal cruelty case.
Pippi the cat was found on Auckland's North Shore last Friday with her ears cut off; she was reunited with her owners after a public appeal.
Inspectors would be doing everything possible to investigate the latest case, Midgen said.
"We want to send a clear message to all Aucklanders that intentionally harming and causing injuries to animals is absolutely unacceptable."
Anyone driving in Greenhithe yesterday who witnessed the incident can call SPCA Auckland (09) 256 7300.
