A couple working from home with a fenced garden does not have the same constraints as a single person in a studio who returns after eight o’clock. Choosing a pet without considering this daily reality risks abandonment a few months later. Let’s take stock of the concrete criteria that guide the choice of the right companion.
Positive list and NAC: the legal framework that restricts your options
Before even comparing dog or cat breeds, a regulatory constraint already filters the choice. The “positive list” project for non-domestic species is currently being tightened: in the long term, only explicitly authorized species will be allowed to be kept. For anyone considering a reptile, ferret, or exotic parrot, this development changes the game.
Specifically, adopting a NAC (new pet) today requires checking its compliance with a registered breeder or a shelter. Pet stores are also facing new penalties for the sale of dogs and cats, which reinforces the distinction between legal channels and informal circuits.
It is recommended to cross-reference the information available on aniwal.fr with the official lists from the Ministry of Agriculture before any adoption process, especially for exotic species.
Housing size and type of animal: deciding without making mistakes
The size of the housing remains the primary filter. In an apartment, an indoor cat or a small rodent (guinea pig, hamster) adapts easily as long as a dedicated space is provided. A large breed dog in a one-bedroom apartment without a balcony, on the other hand, creates stress for the animal and disturbances for the neighbors.

Apartment without outdoor space
Cats not used to going outside live very well indoors if provided with scratching posts, high platforms, and daily stimulation. Freshwater fish are also suitable, provided regular aquarium maintenance is ensured.
House with a garden
A fenced garden opens access to active dog breeds (Australian shepherd, border collie, pointer). It is often thought that the garden is enough: it does not replace walks. A dog that circles in a garden without outside access develops as many behavioral issues as in an apartment.
Daily available time: a criterion often underestimated
A dog requires at least one to two outings per day, plus time for play and socialization. Adopting a dog when working more than ten hours outside the home is rarely viable without a pet-sitting or dog-walking solution.
The cat requires less active presence, but still suffers from prolonged isolation. Two cats together better compensate for the owner’s absence than a single cat.
- Less than two hours per day to dedicate: fish, certain permitted reptiles, hamsters (nocturnal animals that interact little during the day).
- Two to four hours per day: cat, pair of budgerigars, rabbit (which needs daily outings outside the cage).
- More than four hours per day: dog, parrot (which requires sustained social interaction to avoid behavioral issues).
Opinions vary on the question of rabbits: some owners find them very independent, while others point out that a rabbit confined in a cage without outings becomes apathetic within a few weeks.
Veterinary and maintenance budget: plan ahead before adopting
The cost of a pet is not limited to the purchase or adoption fees. Annual veterinary expenses often weigh more heavily than the acquisition price. Vaccinations, sterilization, anti-parasitics, emergency consultations: these costs add up.
A large breed dog costs significantly more in food and care than a cat. NACs like reptiles also add the cost of a heated terrarium, UV lighting, and a specialized veterinarian (not all clinics cover them).
- Dog: food, annual vaccines, deworming, recommended health insurance, grooming depending on the breed.
- Cat: food, sterilization, monthly litter, vaccines, dental cleaning to be planned with age.
- NAC (rodent, bird, reptile): suitable habitat, specific food, consultations with a NAC veterinarian often more expensive.

Children at home: real compatibility between breeds and age groups
The presence of children strongly influences the choice. A pet suitable for children is not simply a “nice” animal, it is an animal whose tolerance threshold for noise, sudden movements, and handling is high.
Dog breeds known to be tolerant with children (golden retriever, labrador, cavalier King Charles) remain safe bets, provided the puppy is socialized as soon as it arrives. An adult cat adopted from a shelter, whose character is already stabilized, can also be suitable if the shelter confirms its tolerance for contact.
For young children, fragile rodents (hamster, mouse) pose a concrete problem: the child risks injuring them while handling. The guinea pig, more robust and naturally sociable, is a better option for a first contact with an animal.
Animal welfare and human well-being: a link less automatic than one might think
Several recent research studies show that there is no overall association between pet ownership and improved health or well-being. The benefit depends on the type of relationship established with the animal and the owner’s living context. Adopting a dog to “combat loneliness” without having the time to care for it produces the opposite effect: guilt, imposed constraints, increased isolation.
Choosing a pet suitable for one’s lifestyle means first accepting that certain situations are not conducive to adoption. A very busy lifestyle, frequent travel, or a too-small living space are not obstacles to be circumvented; they are signals to be respected. The right choice rests on the alignment between the animal’s needs and the conditions that can realistically be guaranteed on a daily basis.
