Overnight pet sitting in Poissy: we stay in your home
We are Leisan and Vincent. In Poissy, we look after your animals in the home they already know, and we sleep there every night of the sit. No boarding, no kennel, no stranger dropping in twice a day: your cat keeps their windowsill, your dog keeps their walk, and your home stays lived in.
What Poissy changes
The old centre, Beauregard, La Coudraie and the riverside: the area is not interchangeable with the rest of the city, and neither is a sit here.
Houses with gardens in Villennes-sur-Seine and Médan, flats and residences in Poissy itself. Riverside properties often slope down towards the water.
Green space nearby: Parc Meissonier, Île de Migneaux, the Seine riverbanks and the Saint-Germain forest.
We also cover Villennes-sur-Seine, Médan, Orgeval and Villepreux.
Cats in Poissy
A cat's territory is the flat itself. Moving them to a boarding facility means changing every smell, every sound and every route at once, which is exactly what most cats handle worst. Staying put removes that problem entirely.
On plots sloping down to the Seine a cat always finds a way out. We check low basement and garage openings before the first night.
We keep the litter tray, the bowls and the sleeping spots exactly where you left them. We feed at your times, with your food, in your quantities.
Dogs in Poissy
The riverside and the Saint-Germain forest give two kinds of walk: long and flat on one side, woodland on the other.
Each town sets its own rules for its parks and squares, posted at the entrances. We read them on site on day one, before the first real walk.
We keep your dog's own route and rhythm. If they have a habit of a long morning walk and a short evening one, we do not reverse it because it suits us better.
What we follow every day
We ask for written instructions before you leave: meals and quantities, timings, walks, litter, prescribed medication, plants, bins, post. We follow them as written. If something needs to change, we ask you first.
We usually send photos every day on WhatsApp. Some owners prefer a message every other day, others a summary each evening. Tell us what suits you.
Access, keys and the building
We collect the keys in person, during the meet-up or just before you leave. We write down the door code, the floor, how the lift works, the name on the letterbox and the caretaker's contact when there is one.
We never leave a set of keys in an unsecured box, and we never hand your home to a third party. There are two of us: Leisan and Vincent. Nobody else comes in without your agreement.
If something goes wrong
We are not vets. We observe, we tell you immediately, and we call the vet you have chosen. The decision stays yours.
Across more than fifty sits, three needed a vet visit: a dog with a hot spot, a cat who stopped using the litter tray, and a check-up after an operation that took place before the sit.
Before you leave we note your usual vet's name and address. For nights and public holidays, the Paris region has round-the-clock options such as Centre Hospitalier Vétérinaire Frégis, VetinParis and home-visit services. We check the current details at the time of the sit rather than rely on an old list.
