(For this post, we'll only be considering cats and dogs)
Sharing a home with an adult child is becoming increasingly common—and so is the question of whether they should be allowed to bring a pet along. Cats and dogs can add warmth and life to a shared household, but they also bring responsibilities, potential complications, and fur—lots of fur.
If you’re weighing the decision, here are the pros and cons to consider before you say “yes,” “no,” or “maybe, but only if the cat doesn’t scratch the furniture and the dog doesn’t chew Dad’s slippers.”
Pro: Companionship and Emotional Support
Pets provide meaningful emotional benefits, especially during times of transition—job changes, breakups, returning from college, or saving for a first home. A wagging tail or a soft purr can help reduce feelings of loneliness and provide comfort in stressful moments.
A pet can also strengthen the relationship between you and your child—shared laughter at their antics or joint walks can become a pleasant part of daily life together.
Con: Additional Noise, Smell, and Cleanup
Let’s be honest—a cat may be low maintenance compared to a dog, but a litter box is not exactly a scented candle. Dogs bring barking and muddy paws; cats may leave fur on every fabric surface in a five-foot radius.
If cleanliness, odors, or noise are a point of tension in your household, introducing an animal might amplify frustrations rather than soften them.
Pro: Pets Encourage Responsibility and Routine
Allowing a pet can be a positive opportunity for your adult child to demonstrate accountability. Pets need feeding, exercise, grooming, and vet visits—tasks that build routine and discipline.
If your child is preparing for independent living, pet ownership can serve as valuable practice for managing time, money, and household responsibilities.
Con: The Responsibility Might Fall Back on You
Here’s the flip side: If your child’s work schedule is unpredictable, or they forget tasks easily, you may become the default caregiver.A dog needing a mid-day walk or a cat that demands breakfast at 6 a.m. doesn’t know whose turn it is—and often, whoever is home will respond.
Before agreeing, it’s worth asking:
Who walks the dog in the rain?
Who cleans the litter box?
Who pays for vet bills?
Clarity upfront avoids arguments later.
Pro: A Built-In Mood Booster for the Whole Household
Animals have an incredible ability to lighten the atmosphere at home. A playful dog nudging you for belly rubs or a cat curling up in your lap can bring joy and reduce tension. Pets don’t take sides, hold grudges, or bring up Thanksgiving 2012.
Sometimes, their simple presence brings the household closer together.
Con: Potential Damage and Financial Costs
Scratched doors, chewed shoes, damaged carpets, or unexpected medical emergencies—pets come with price tags. Even a well-trained dog or calm indoor cat can have an occasional accident or moment of destructive enthusiasm.
If financial stress already exists in your household, the cost of food, grooming, vaccinations, or pet deposits (if you rent) may outweigh the benefits.
Pro: A Sense of Security
A dog’s bark can deter intruders, and even a cat’s alert behavior can signal that something is unusual. Pets help many homeowners feel safer and more aware of their surroundings.
While this shouldn’t be the primary reason to allow a pet, it can be a welcome bonus.
Con: Travel and Lifestyle Restrictions
A spontaneous weekend trip or last-minute invite becomes more complicated when a pet depends on someone at home. Dogs need sitters or boarding. Cats need food, water, and a clean litter box. Someone must always be responsible—and that someone might end up being you.
Final Thoughts: A Yes—With Conditions
Allowing your adult child to have a cat or dog while living with you can be a rewarding experience, full of wagging tails, warm snuggles, and memorable moments. However, it requires honest communication and mutual respect.
Consider establishing expectations ahead of time:
Who pays for the pet?
Where can the pet go? (Bedrooms? Furniture? Yard?)
Who handles cleaning, feeding, and vet care?
When boundaries are clear, pets can enhance your home—not complicate it. The key is making a decision that respects both your household and your child’s desire for companionship.
