"Firstly, you are getting an animal that is vaccinated and desexed and you are not going to perpetuate the problem.
"Also the fact that you are saving a life because these animals are the ones that are unwanted - they are the strays and neglected and the abandoned, and they deserve another chance at life."
The kitten season, which began early this month, has seen all three SPCAs struggle with a high number of newborns.
Central Hawke's Bay SPCA centre manager Renee Hickey said they had been inundated with animals leading up to Christmas.
"We are very busy right now. In the past two weeks, we have received over 50 kittens. There have been a lot that have appeared from out of nowhere."
SPCA Hastings and Districts chairwoman Daileen Kensington said "their goal was to rehome every animal, wherever we can".
"Being part of the SPCA, we see some very sad cases."
While all three SPCA shelters urge people to consider adopting a pet, they need to be aware of the commitment involved.
