MyDog Versus Cat Cost
A dog in the US costs about $100 to $250 per month in 2026, and a cat costs about $60 to $150 per month. A dog costs about $1,500 to $4,500 in the first year, and a cat costs about $800 to $2,500 in the first year. Over a lifetime, a dog costs about $15,000 to $45,000, and a cat costs about $10,000 to $30,000. A dog costs more in food, vet care, insurance, grooming, training, and boarding. A cat costs less in all of those, but it needs litter, and it needs a scratching post, a litter tray, and a carrier. The cheapest pet to own is a domestic shorthair cat, and the most expensive pet to own is a large unhealthy dog.
Choosing between a dog and a cat is not only about cost. A dog needs walking, training, and company, and it gives you a loyal, social companion that goes everywhere with you. A cat needs less time, less space, and less training, and it gives you a quiet, independent companion that is happy at home. Cost matters, and this page compares the two honestly, with real price ranges checked in Nov 2026, so you can choose with your eyes open. Use it with the breed guides. Our dog cost guide and cat cost guide give the full monthly breakdown for each, and our Golden Retriever cost guide and Maine Coon cost guide give the breed level detail.
Every price here is a range checked in Nov 2026. Published sources disagree because the price depends on breed, size, age, and location. Use the ranges to plan, then get local quotes for food, vet care, and insurance where you live.
Dog versus cat cost, month by month
| Cost | Dog per month in the US | Cat per month in the US |
|---|---|---|
| Food | $40 to $110 | $20 to $55 |
| Treats | $10 to $30 | $5 to $15 |
| Routine vet care, averaged | $25 to $65 | $20 to $50 |
| Pet insurance | $25 to $90 | $15 to $50 |

| Litter | Not needed | $10 to $30 |
| Training, averaged | $10 to $40 | Not needed |
| Toys and supplies | $10 to $30 | $5 to $20 |
| Total per month | $100 to $250 | $60 to $150 |
A dog costs more in almost every row, because a dog is larger, eats more, needs more medicine, and needs training and grooming. A cat costs less, but litter is a cost that a dog does not have, at $10 to $30 a month. A small dog, such as a Chihuahua at $80 to $150 a month, costs about the same as a large cat, such as a Maine Coon at $110 to $190 a month, so breed matters as much as species. See our cheapest breeds guide and most expensive breeds guide for the full ranking.
Dog versus cat cost, first year and lifetime
| Cost | Dog in the US | Cat in the US |
|---|---|---|
| Purchase price, breeder | $800 to $3,500 | $400 to $2,000 |
| Adoption fee, rescue | $100 to $500 | $50 to $300 |
| First year total | $1,500 to $4,500 | $800 to $2,500 |
| Annual cost, adult | $1,200 to $3,000 | $720 to $1,800 |
| Lifetime cost | $15,000 to $45,000 | $10,000 to $30,000 |
| Life expectancy | 10 to 13 years | 12 to 16 years |
A cat lives longer than a dog, on average, but costs less per month, so the lifetime cost is lower even though the cat lives longer. A dog costs more in the first year, because the puppy price is higher, training costs more, and the first vet visits cost more. A cat costs less in the first year, because the kitten price is lower, and a cat needs less training and less equipment.
Food cost, dog versus cat
A dog eats more than a cat, because a dog is larger. A medium dog of about 20 kg eats about $50 to $80 of food a month. A cat of about 4 kg eats about $25 to $45 of food a month. A large dog of about 30 kg eats about $60 to $110 a month, which is more than twice the food cost of a cat. Use our Dog Food Cost Calculator and Cat Food Cost Calculator to compare food by cost per day for your pet's weight, and our Dog Feeding Calculator to work out how much food a dog needs each day.
Vet and insurance cost, dog versus cat
A dog costs more for vet care and insurance than a cat. Routine vet care costs about $25 to $65 a month for a dog and $20 to $50 a month for a cat, averaged across the year. Pet insurance costs about $25 to $90 a month for a dog and $15 to $50 a month for a cat. Emergency vet care costs more for a dog too, because a dog is larger and needs more anaesthetic and more medicine. A single emergency surgery for a dog costs $1,500 to $5,000, and for a cat it costs $1,000 to $3,000. See our pet insurance cost guide for prices by breed and age, and a break even worked example.
Grooming and training cost, dog versus cat
A dog needs more grooming and training than a cat. Dog grooming costs $40 to $110 per session, and most dogs need grooming every 6 to 12 weeks. Cat grooming costs little, because most cats groom themselves, and a short haired cat needs only brushing at home. A long haired cat, such as a Persian, needs daily grooming at home and professional grooming every 6 to 8 weeks, at $50 to $100 per session. Dog training costs $150 to $500 for a group class, and $50 to $150 per hour for a private trainer. A cat needs little training, and most cats learn to use a litter tray in a few days. See our dog grooming cost guide for prices by size and coat type.
Travel and boarding cost, dog versus cat
A dog costs more to travel with and to board than a cat. Boarding a dog costs $30 to $75 per night, and a two week holiday costs $400 to $1,000. Boarding a cat costs $25 to $60 per night, and a two week holiday costs $350 to $800. A cat sitter who visits your home costs $20 to $40 per visit for a cat, and $25 to $50 per visit for a dog. A dog walker costs $15 to $30 per walk. A cat can stay alone for a day with food, water, and a clean litter tray, while a dog needs a walk and a toilet break every few hours. If you travel often, a cat is cheaper and easier to leave, and that travel saving can be $500 to $1,000 a year.
Time cost, dog versus cat
Time is the biggest difference between a dog and a cat, and it is a cost that money cannot fix. A dog needs walking 2 to 3 times a day, for 30 to 60 minutes each time, and that is 1 to 3 hours of your day. A puppy needs toilet breaks every 2 to 3 hours. A cat needs daily feeding, litter cleaning, and play, for about 30 minutes a day. If you work long hours, a dog may need a walker at $15 to $30 per walk, or day care at $25 to $50 per day, and that adds $300 to $1,000 a month to the cost. If you cannot give a dog the time it needs, a cat is a better choice. A dog that does not get enough exercise and company becomes bored, destructive, and anxious, and that costs money in damage and vet bills.

Which pet fits your budget
Choose a dog if you can afford $100 to $250 a month for 10 to 13 years, plus training and travel costs, and you have 1 to 3 hours a day for walking, training, and play. Choose a cat if you can afford $60 to $150 a month for 12 to 16 years, and you have 30 minutes a day for feeding, litter, and play. Choose a small healthy dog if you want a dog but your budget is tight, because a Chihuahua costs $80 to $150 a month, which is about the same as a large cat. Choose a domestic shorthair cat if you want the cheapest pet to own, at $50 to $100 a month. Either way, plan for hidden costs too, and see our hidden costs guide before you commit.
Frequently asked questions
Is a dog or a cat cheaper to own?
A cat is cheaper. A cat costs about $60 to $150 a month in the US in 2026, and a dog costs about $100 to $250 a month. A cat also costs less in the first year and over a lifetime.
How much does a dog cost versus a cat over a lifetime?
A dog costs about $15,000 to $45,000 over a lifetime, and a cat costs about $10,000 to $30,000. A cat lives longer on average, but costs less per month, so the lifetime total is lower.
Do cats need insurance too?
Yes, if one vet bill of $1,500 would be hard to pay at once. Cat insurance costs $15 to $50 a month, and one emergency surgery for a cat can cost $1,000 to $3,000.
Which pet is better for a flat?
A cat is usually better for a flat, because it needs less space, less walking, and less noise. A small dog can work in a flat too, if you walk it 2 to 3 times a day and train it well.
Which pet is better if I work long hours?
A cat is better, because it can stay alone for longer and needs less time each day. A dog needs a walk and a toilet break every few hours, and a walker or day care adds $300 to $1,000 a month to the cost if you are out all day.

Sources and how we priced this
Prices in this guide are ranges, not single facts, because published sources disagree. We used the American Pet Products Association 2025 and 2026 industry figures, Rover 2026 cost of dog ownership reports, the PDSA PAW Report and PDSA cost guides for the UK, the American Animal Hospital Association and the National Research Council feeding guidance, and published insurer and vet price lists in the US and the UK. All prices were checked in Nov 2026 and are shown in US dollars unless a UK section says pounds. Where a source gave one number, we widened it into a range to reflect size, breed and location.
