Short answer
Yes, you can have more than one emotional support animal if a licensed clinician supports a disability-related need for each one, and your letter should name every animal. Landlords consider each animal separately. Since May 2026, HUD presumes requests are reasonable only for trained animals, so each untrained ESA needs a clear disability-related reason.
2026 update: In May 2026, HUD changed how it enforces animal requests under the Fair Housing Act. It now presumes a request is reasonable only when the animal is individually trained to do disability-related work or tasks. The Act itself didn't change, you can still bring your own fair housing claim, and some state laws, such as California's, still protect emotional support animals that aren't trained. What changed and what it means for you.
Plenty of people live with two cats, or a dog and a cat, and depend on both. The law doesn't force you to choose. But a request for several animals gets more attention from a landlord than a request for one, so it helps to understand how these requests are judged.
What the law says about multiple ESAs
Under the Fair Housing Act, an emotional support animal is a reasonable accommodation for a person with a disability. Nothing in the law caps the number of animals. Instead, each animal is part of the accommodation request, and each one needs to be supported by a disability-related need.
In practice, a landlord looks at the request as a whole and asks two questions. Is there reliable documentation that you need each animal? And is the request reasonable, meaning it doesn't impose an undue burden or create a direct threat to others?
What the clinician looks at
A clinician doesn't approve animals because you happen to own them. They consider whether each animal provides support that eases symptoms or effects of your disability. Sometimes two animals play different roles. A dog may give structure and a reason to go outside, while a cat helps with sleep and evening anxiety. Sometimes the support overlaps, and the clinician may decide one animal is enough. That decision is theirs to make.
Be specific in your assessment. Describe what each animal does for you. "Both of them help" is weaker than explaining what changes when each one is with you.
What a landlord can weigh
A landlord can't refuse just because you have more than one animal or because the lease allows only one pet. They can consider:
- The size of the home. Three large dogs in a studio apartment is a harder request than two cats in a two-bedroom.
- Local codes. Some cities limit the number of animals per household for health or zoning reasons.
- Each animal's behavior. A landlord can deny a specific animal that poses a direct threat or causes serious damage that can't be reduced, based on that animal's actual conduct.
- Documentation for each animal. If the letter covers one animal and you live with three, expect questions about the other two.
You can ask for breed and weight limits to be set aside for each animal. See ESA breed and weight restrictions for how that works since HUD's 2026 change.
How multiple ESAs appear on a letter
The clearest approach is one letter that names each animal and its species, for example "her dog, Scout, and her cat, Juniper." That tells the landlord exactly which animals the accommodation covers and avoids a second round of paperwork.
With ESA Letter US, the ESA housing letter is $99 for the first animal and $25 for each additional animal, up to three animals on one letter. The clinician still decides on each animal, and you get a full refund if you're not approved.
Different species
Emotional support animals don't have to be dogs. HUD's 2020 guidance, withdrawn in 2025, described animals commonly kept in households, such as dogs, cats, small birds, rabbits, hamsters, gerbils, other small rodents, fish and turtles, as generally reasonable to request. Since May 2026, HUD presumes a request is reasonable only when the animal is trained to do disability-related tasks, so each untrained animal needs a clear disability-related reason. Unusual animals need more explanation of why that specific animal is needed. A mix of a dog and a cat is common and rarely raises questions on its own.
Tips for a smooth multi-animal request
- Request all animals at once. Adding animals one at a time makes each new request look like an afterthought.
- Name every animal on your letter. Include the species and name for each one.
- Be ready to describe each animal's behavior. Vaccination records and a short note about temperament can help.
- Think about the space. If you're apartment hunting, choose a unit that suits the animals you have.
- Update your letter when things change. If you add a new animal later, it needs to be covered too.
A service dog and an ESA together
Some people have a psychiatric service dog and an emotional support animal, such as a trained dog plus a cat at home. That's allowed. The service dog is covered for housing and public access, and the ESA is covered for housing only. If you need both letters, the ESA and PSD combo is $199.
Frequently asked questions
Is there a limit on how many emotional support animals I can have?
Federal law doesn't set a number. Each animal must be supported by a disability-related need, and the overall request has to be reasonable for your home. Local codes on animals per household may also apply.
Can my landlord allow one ESA but refuse the second?
A landlord can only refuse an animal for a valid reason, such as missing documentation for that animal, a direct threat based on the animal's actual behavior, or an undue burden. A one-pet lease rule isn't enough on its own.
Do I need a separate ESA letter for each animal?
No. One letter can name several animals. Listing each animal by name and species is the clearest approach.
Can my ESAs be different species?
Yes. Dogs, cats, small birds, rabbits and other common household animals can all be emotional support animals, and a household can include more than one species.
How much does it cost to add animals to an ESA letter?
With ESA Letter US, the letter is $99 for the first animal and $25 for each additional animal, up to three animals on one letter.

Find out whether you qualify for an ESA letter
Answer a few questions and a mental health professional licensed in your state reviews your assessment. If you're approved, your Fair Housing Act letter arrives as a PDF, typically within 24 to 48 hours of your evaluation.* $99 one-time, $25 per additional animal, $79 to renew each year. Full refund if you're not approved.
*Arkansas, California, Iowa, Louisiana and Montana require a 30-day client–provider relationship before a letter can be issued, so the letter issues after day 30.
