A cat in a rented flat costs $200 to $500 up front as a pet deposit, plus $25 to $50 a month in pet rent at roughly 1 in 3 buildings that charge it at all. Over a 12-month lease that is $500 to $1,100 before the cat eats anything. The deposit is recoverable and the monthly rent is not, and landlords routinely blur the two in conversation. Three signed papers, two sets of dated proof and five move-out actions decide whether the $200 to $500 comes back in 14 to 30 days or disappears into a carpet invoice.
Deposit, fee, rent: 3 different lines
A refundable pet deposit of $200 to $500 is held and returned minus damage. A non-refundable pet fee of $100 to $300 is income and never comes back. Pet rent of $25 to $50 a month is charged for the privilege of having the animal at all. Ask which of the 3 appears on the lease, because a building that charges all 3 can take $1,100 in year 1 and still bill you for the carpet. Some US states cap total deposits at 1 to 2 months of rent, and in England the Tenant Fees Act has capped the whole deposit at 5 weeks of rent since 2019, which is why UK landlords increasingly use pet rent or a pet clause instead of a separate deposit.
3 papers to sign before the cat arrives
1) A pet addendum that names the species, the number of animals (1 cat, not pets permitted), a weight limit if any, and the exact clause on damage. 2) A deposit receipt that splits refundable from non-refundable in figures, not adjectives: $300 refundable, $100 non-refundable, returned within 21 days of move-out. 3) A move-in condition report signed by both sides, with the cat written into it, plus written approval by email or message if the addendum is not ready on day 1.
Verbal permission is worth nothing at move-out, 12 months later, when the property manager has changed twice. A one-line email saying the cat is approved is enough to survive that turnover, and it costs 30 seconds to request.
2 kinds of proof, kept in 2 folders
The first folder proves the cat: vaccination record, rabies certificate, microchip number (15 digits), and the adoption or foster-to-adopt contract showing the date the animal arrived. That folder answers the question every landlord asks at renewal: is this the same 1 cat, and is it legal in this city.
The second folder proves the flat. Take 40 to 60 dated photos on move-in day, including 4 close-ups of each carpet edge, the skirting boards, and the spot where the litter box will sit, plus a 3-minute video walk-through with the front door visible at the start. Photos taken at 10:00 with daylight and no flash read as evidence; photos taken at night with a flash read as argument.
5 items at move-out
1) A carpet cleaning receipt from a company the lease names, $150 to $300 for 2 rooms. 2) The same 4 carpet corners photographed again, same angle, same daylight. 3) Odour treatment if the litter corner smells: ozone for 2 to 4 hours at $100 to $200, or an enzyme soak at $30 to $80. 4) A joint walk-through within 14 days, signed by both parties on the same sheet. 5) A forwarding address in writing, because a deposit mailed to the old flat is a deposit you never see.
Skip step 4 and the process becomes 1-sided: the landlord inspects alone, invoices alone, and in most US states the 14-day to 30-day return clock starts anyway.
What each line costs
| Line | US (USD) | UK (GBP) | Returned to you |
|---|---|---|---|
| Refundable pet deposit | 200 to 500 | 100 to 300 | Yes, in 14 to 30 days |
| Non-refundable pet fee | 100 to 300 | 50 to 150 | No |
| Pet rent, per month | 25 to 50 | 10 to 25 | No |
| Carpet clean at move-out | 150 to 300 | 60 to 150 | Only with a receipt |
| Ozone or enzyme odour treatment | 30 to 200 | 20 to 120 | Only with a receipt |
| Year 1 total, 12-month lease | 780 to 2,000 | 380 to 1,050 | 200 to 500 of it |
The gap between the two columns is mostly pet rent: 12 payments of $25 to $50 is $300 to $600, which is often larger than the deposit everyone argues about. Run both numbers through the cost calculator before signing, because a $200 deposit with $50 rent is the more expensive lease.
When the lease says no pets at all
A no-pet clause is not absolute in the US: a assistance animal supported by a clinician's letter is generally handled as a reasonable accommodation, with no pet deposit and no pet rent, because it is not a pet under fair housing rules. That route is for animals that do a job, and using it for a cat that does not is the fastest way to lose both the accommodation and the tenancy. In the UK, the Model Tenancy Agreement was changed in 2021 so consent for a pet is the default and refusal must be in writing within 28 days.
The balcony and window question
Landlords ask about screens for a reason: a cat that falls from a 4th-floor window is a repair bill and a liability claim. Fit screens before the inspection, not after, and mention the mesh spec — 18 by 16 strands per inch is the common minimum for a cat, and a balcony net at $60 to $200 removes the argument entirely. The full list of what a landlord will look at is in the window and screen safety guide.
6 steps before you sign
- Ask for the 3 numbers separately: deposit, fee, monthly rent.
- Get the pet addendum signed, with the cat named.
- Photograph 40 to 60 move-in shots and a 3-minute video.
- Put both return windows in the calendar, at move-out and at 21 days after.
- Book the carpet cleaner the lease names, not the cheapest one.
- Keep receipts in the same folder as the photos, in date order.
Frequently asked
Is a $300 pet deposit refundable if the cat caused no damage?
It depends on the wording, not the amount. A deposit is refundable by definition, usually within 14 to 30 days of move-out and minus itemised deductions; a fee is not. Ask for the split in figures on the receipt and photograph it. Without a signed move-in condition report, a landlord can attribute old carpet wear to the cat, and the $300 becomes a $180 cleaning charge with no way to argue.
Can a landlord charge both a pet deposit and monthly pet rent?
In most US states, yes, unless local law caps it. Expect $200 to $500 once plus $25 to $50 a month, which is $500 to $1,100 in year 1. England caps the total deposit at 5 weeks of rent, so a separate pet deposit usually cannot be added there and pet rent or a pet clause takes its place. Always ask which of the 3 lines is on the lease.
What if the cat scratches a door frame before the lease ends?
Fix it before the walk-through rather than argue about it after. A scratched frame is a $40 to $120 repair with wood filler and paint, against a deduction of $150 to $300 taken from the deposit. Keep the receipt either way. Photograph the repair next to the move-in photo of the same frame, so the before-and-after reads as maintenance instead of damage.
