According to the RSPCA Australian Statistics for the 2017/18 year, they received over 132,000 animals that needed to be re-homed or re-claimed.
One Lithgow group, Hearts for Animals, is trying to get that statistic down.
The group which is run by husband and wife Glenn and Joanne Rees, has been up and running since 2003.
"We rescue and re-home animals that we get from the pound or ones that have been surrended to us or we've found on the streets," Mr Rees said.
"We micro chip them, de-sex and make sure they are vaccinated."
Mr and Mrs Rees have been volunteering in animal welfare work for over 20 years and said they saw a need for a country group.
"We thought this area needed a group because it doesn't matter if you're in the city or country, animals are still being left," he said.
According to Mr Rees, it is the kittens and cats that are popular adoption pets for Lithgow locals.
"The dogs tend to get adopted down in Sydney," he said.
Currently the group is looking after 12 kittens and cats and around 20 dogs, that are all looking for homes.
"The whole point of what we do is to save lives, the animals that normally get abandoned are put to sleep, so adopting an animal is really giving it a second chance," he said.
To help these pets get adopted Frontline Pet Care, PetRescue and PETstock have partnered together to raise awareness of pet adoption through the donation of 21,000 bottles of shampoo to organisations across Australia.
Hearts for Animals was one of the lucky organisations chosen to receive a donation.
"This will help us a great deal, we are so grateful, we never get many of these donations so we can't thank them enough," Mr Rees said.
According to Mr Rees, some of the animals that come into their care are quite 'manky'.
"So this will help with the adoption process, if we can get them looking their best," he said.
"It isn't just normal animal shampoo but medicated shampoo for animals that might have itchy skin for example.
"We can't thank Frontline enough for the support, it will keep us going for a long time."
Mr Rees said that a lot pf people privately donate pet food and leads, which is appreciated.
"Without all this extra help we couldn't do the re-homing," Mr Rees said.
Once the group receives the applications for certain pets, they will go through and judge who they think is best suited to the animal.
"We then do a test with the person and animal to make sure they are suited, and for dogs we will go and check fencing," he said.
"It's basically a meet and greet, and an adoption interview."
The group also relies on foster carers to look after some of their animals.
"The kitten carers are amazing, we couldn't do what we do without them," he said.
"It also allows the animals to be in a normal home environment, and we can see their temperament."
