It all began with "Saturday afternoon conversations" between Dr Dilly Abeyawardane and vet nurse Fiona Russell about helping those in need with veterinary care in the capital.

But it wasn't until they met Heather Bates - who's nephew was part of the launch of Pets in the Park in Sydney in 2012 - they set about bringing the initiative to the capital.

After a year's worth of preparation, the team ended up launching in 2017.

"Anyone who is homeless or at the risk of being homeless can come and see us, they just need a referral letter from their service provider stating their circumstances and that's valid for six months and during that time they can come to as many clinics as they wish," Dr Abeyawardane said.

Ms Russell added: "There are other means of accessing veterinary care for clients who are on a low income or who are underprivileged however we cater to a certain section of society whereby there are clients who literally slip through the cracks".

"While their pets would have been denied veterinary care in the past, now they are able to access our services for free."

Run out of the Early Morning Centre on Northbourne Avenue, the team of five vets and five vet nurses will see 25 pets on average come through the clinic during the two hours that they open for on the first Sunday of every month.

This can be things as simple as vaccinations, worming and flea control, but every three months they also host a surgical clinic which can be to perform any desexing, dental or x-ray work.

"We view our services as being incredibly important, not just in terms of the perspective of welfare but also from the perspective of controlling population," Ms Russell said.

"[This is] in terms of not having unwanted pets, extra pets, that would not be able to find homes otherwise and therefore adding additional burden to shelters.

"We love what we do, ultimately, and I know for a fact that our clients and our patients really appreciate how we contribute to the lives of their pets.

"In a roundabout way, in trying to improve the welfare of their pets ... we are hoping that we could also help our clients who are either going through a really tough time or challenging time in their life or a disadvantage that renders them homeless.

"It enables them to rest easy knowing that their pets have been cared for, therefore they can concentrate on improving their circumstances."
