Dr Schneider said pet owners should be allowed no more than four cats per household.
"... there are a number of cat colonies in and around Tauranga.
"These animals are not healthy, some are missing an eye, others have skin diseases."
Forcing owners to register and microchip their cats would establish a sense of ownership and keep numbers down, she said.
Avenues cat lover Michelle McDonnell microchipped her cat, Andy, and would register him if council adopted the proposal.
"He is my baby and if I ever lost him, I would want him back," Mrs McDonnell said.
However, her husband, Tauranga Vets managing director David McDonnell, questioned the proposal, asking why Tauranga would be the first to test "something as political as that."
"I would want to see the evidence that would work first," he said. "We encourage our clients to microchip but it is voluntary and until there is some really good evidence to support the need to enforce that then I do not see the point.
"I don't think council should bow to one small group putting on pressure. I think it is something council should let the public decide."
Mayor Stuart Crosby said he would be reluctant to introduce rules for registering and microchipping cats.
