And whilst there are many animal rescue centres able to help out, the fact that cat numbers are rarely controlled causes problems for both local people and the mairie.
Lynn Stone, of the charity Les Amis des Chats, is involved in a project in the Lot et Garonne that aims to tackle the issue where the plan is to trap, neuter and return the cats.
"We've calculated that just one single female cat can, in just three years, give rise to around 2,000 cats and kittens so it is clear that something has to be done," Lynn said.
"Unfortunately some places look to poison or shoot cats which just creates a vacuum that is filled by other cats, that's why we look to humanely capture cats, take them to the vets to get them checked over and neutered, before releasing them back where they were first found.
"Such a system has proven effective all over the world and we believe it is the only way to deal with a colony of cats."
Les Amis des Chats was started in 2000 by a local vet in the village of Roquecor, where stray cats were causing problems of disease and infections, as well as proving a nuisance to visitors and local businesses.
A few years later Lynn became involved with the charity's work after looking after some cats, and being an artist who works from home enabled her to assist with the administration and fund raising side of things.
"Like most people I started helping by adopting two cats and then began donating pieces of my artwork to raise money, but quickly I ended up completely involved, so today I have the refuge and adoption centre in our home," Lynn said.
"And our work has also seen us offer support to 32 other communes where we work with the mairie and local volunteers to organise the trapping and tracking.
Clearly such a venture can not run on just the goodwill of volunteers, so a major part of Lynn's work is in organising fund raising events and looking at ways to generate income.
"Our work is supported by the Blue Cross and we have also received funds from the RSPCA for individual projects such as the refurbishment of the enclosures we have," Lynn said.
"There is usually some fund raising initiative running every month, and we have around 200 members who donate €20 a year, and whilst some of the mairies we assist do help out some don't, although it costs €200 to deal with each cat.
"We have a calendar that features the work from our art and photography competitions, plus we will often receive a signed book from the author Joanna Harris or artwork from cat artist Lesley Anny Ivory, but people themselves also host events such as auctions or car boot sales with the money being passed on.
"Later this year we are looking forward to running a gala that will draw together people's stories about their cats into a book, and we've just started a cat sponsorship service that lets people help us out whether they live in France, the UK or further a field."
