You're making ramen in a 12-ounce mug, balancing it on a textbook, and your roommate's puppy has just discovered that the dorm hallway is a racetrack. You need a gate that keeps the dog in one zone, fits a doorway or a dorm room opening, and costs less than a pizza delivery run — ideally under $35. The catch is that most cheap gates are wide, bulky, and designed for houses with staircases, not for 200 square feet of shared living space.

Here's the honest truth up front: the selection of pet gates that are genuinely under $35 is thin, and a few of the well-known names in this category sit right at or slightly above that line depending on the size and finish you pick. So this guide focuses on what actually fits a small space, plus a few products that are worth knowing about if you can stretch the budget or if you're really shopping for a pet rather than a baby.

What actually matters
- Footprint and opening width. In a dorm, the gate has to span a doorway or a narrow room divider, usually somewhere between 28 and 38 inches. Measure the opening before you buy anything, and check whether the gate needs a wall cup or pressure mount — many cheap gates do not come with hardware for both.
- Mount type. Pressure-mounted gates need two flat, sturdy surfaces and no drilling, which is ideal for a rental or a dorm where you can't put holes in the wall. Hardware-mounted gates are more secure but require screws.
- Swing versus walk-through. A gate with a walk-through door is worth the extra few dollars in a small room, because you'll be stepping over it twenty times a day otherwise. A fixed panel with no door gets old fast.
- Height. Most budget gates run about 23 to 30 inches tall. That's fine for a small dog or a cat; it is not going to hold a determined 60-pound dog.
- Weight and storage. If you're moving the gate between a doorway and a closet, lighter is better. Metal gates in this range typically weigh 8 to 15 pounds.
- What it's actually rated for. Manufacturer specs list a recommended pet height or weight range, and owner reviews will tell you whether that rating holds up. Read both, because the spec is the marketing claim and the reviews are the reality.
North States Supergate
Rough price band: typically $25 to $40 depending on the model and finish.
What makes it a good pick: North States has been making pressure-mounted gates for years, and the Supergate line is the one most often recommended for tight doorways and odd-shaped openings. The standard versions are pressure-mounted, so no drilling, and the narrower configurations are designed for exactly the kind of opening you find in a dorm or apartment. Owner reviews frequently mention that it installs in a few minutes without tools.
Real downsides: the cheaper models are basic — usually a simple swing panel with a latch, no walk-through door on every version, and the plastic components feel light. The height is modest, generally in the 26 to 30 inch range depending on the model, so it's a barrier for small pets, not a containment system for a large dog. Also, the sub-$35 versions tend to be the narrower ones, so measure carefully.
Who should buy it: a student or renter who needs a no-drill gate for a doorway and has a small dog or a cat.
Summer Infant Multi-Use
Rough price band: usually $30 to $50 depending on the configuration.
What makes it a good pick: the Multi-Use line is a pressure-mounted gate that can also be configured as a freestanding play yard in some versions, which is genuinely useful in a small room. The walk-through door and one-hand latch are the features people actually use every day. Specs generally put these around 30 inches tall, which is a reasonable middle ground.
Real downsides: this is a baby gate first, so the opening width and the accessory pieces are designed around child safety standards, and some configurations push past the $35 mark. The freestanding setup takes up more floor space than a plain doorway gate. Owner reviews sometimes note that the pressure mounts need a solid, flat surface — a hollow dorm door frame can be fussy.
Who should buy it: someone who wants a walk-through door and might use the freestanding mode in a small room.
Richell Wood Pet Gate
Rough price band: often $60 and up, so this is a stretch pick, not a budget one.
What makes it a good pick: Richell's wood gates are the ones to look at if you care about how the gate looks in a small space. A wood gate reads as furniture rather than baby gear, which matters when your living room is also your bedroom. These are typically freestanding or hardware-mounted panels with a walk-through door, and the build quality is a step up from plastic.
Real downsides: price, clearly. It's well above $35 in most sizes. The wood construction also means more weight, so it's not something you'll move around casually. And freestanding wood panels take up real floor footprint — the opposite of what a tiny room wants.
Who should buy it: someone who can stretch the budget and wants a gate that doesn't look like a gate.
Amazon Basics Cat Tree
Rough price band: typically $30 to $50 depending on the size.
What makes it a good pick: if the actual problem is a cat that needs its own territory rather than a dog that needs containment, a small cat tree can solve the same conflict — it gives the cat a vertical zone the dog can't reach. The Amazon Basics Cat Tree is a compact, plush-covered unit that fits in a corner, and it's a cheaper way to separate animals in a small room than fencing off floor space.
Real downsides: this is not a gate, and it won't block a doorway. Assembly is required, and owner reviews often mention that the platforms are sized for average cats, not large ones. The base can wobble on carpet unless you snug it against a wall.
Who should buy it: a student with a cat and a dog sharing one room, where vertical separation is more practical than a barrier.
Amazon Basics Cat Scratching Post
Rough price band: usually $20 to $30.
What makes it a good pick: the smallest footprint option on this list. A single scratching post takes up roughly a square foot of floor and gives a cat a place to be that isn't under your desk or on your roommate's bed. If your "gate" problem is really about keeping a cat out of a specific zone and redirecting scratching, this is the cheapest fix here.
Real downsides: it's a post, not a barrier. Stability varies — taller posts in this price range can tip if a cat launches at them, and owner reviews sometimes mention that the base needs to be against a wall. Sisal wear is normal after a few months of heavy use.
Who should buy it: anyone who needs a tiny-footprint cat solution and has no interest in a gate at all.
Amazon Basics Cat Scratching Post
PetFusion Ultimate Cat Scratcher
Rough price band: typically $30 to $45.
What makes it a good pick: this is a lounge-style cardboard scratcher, and it doubles as a low resting spot. For a dorm room, it's flat and slides under a bed or against a wall, so it takes up almost no usable floor space. The replaceable cardboard inserts are a nice touch if you plan to keep it long term.
Real downsides: cardboard sheds. In a small room, you will notice the bits. It also offers no containment function whatsoever, and the reversible insert only buys you so much time before you're buying refills.
Who should buy it: a cat owner in a genuinely tiny room who wants a flat, tuck-away option.
PetFusion Ultimate Cat Scratcher
Pawz Road Cat Scratcher with Catnip
Rough price band: usually $20 to $35.
What makes it a good pick: it's a curved scratcher that typically ships with a bit of catnip, which helps speed up the "will the cat actually use this" question. The curved shape gives a cat something to stretch against, and it's light enough to move with one hand.
Real downsides: curved cardboard units can be awkward to store and don't stack flat like the rectangular ones. Durability depends heavily on how aggressively your cat scratches — heavy scratchers can go through one in a couple of months.
Who should buy it: a student who wants a cheap, low-commitment way to give a cat its own spot in a shared room.

The bottom line
If you genuinely need a barrier under $35 for a doorway in a small space, the North States Supergate is the pick that fits the brief — pressure-mounted, no drilling, and narrow enough for a dorm opening, as long as your pet is small and you measure first. If you can spend a bit more and want a walk-through door, the Summer Infant Multi-Use is the more livable daily option. And if your real problem is a cat and a dog sharing one room rather than a doorway to block, skip the gate entirely: the Amazon Basics Cat Scratching Post or the Pawz Road Cat Scratcher with Catnip solves the same conflict for less money and a fraction of the floor space.
Frequently Asked Questions
Do I need to drill holes to install a pet gate in a dorm?
Not necessarily. Pressure-mounted gates like the North States Supergate are designed to hold in place without screws, which is why they're the usual choice for renters and dorm rooms. They do need two flat, solid surfaces to press against, so a flimsy or hollow door frame can be tricky — check that the frame is sturdy before you commit.
How wide an opening can a cheap pet gate cover?
It varies a lot by model. The budget-friendly configurations in the North States Supergate and Summer Infant Multi-Use lines are generally built for standard doorways and narrow openings, while wider spans often require extension pieces that can push the price up. Measure your opening first, then confirm the gate's listed width range before buying.
What's the cheapest way to keep a cat and a dog apart in a small room?
Vertical and flat space is usually cheaper than a barrier. The Amazon Basics Cat Scratching Post takes up roughly a square foot of floor, and the PetFusion Ultimate Cat Scratcher is flat enough to slide under a bed, so both give a cat a zone the dog can't reach without fencing off any floor space at all.
