As of September 11, 2026, no verified veterinary-industry launch or formal standard specifically called "Cat Apartments" has been identified. The closest documented example is Peggy Adams Animal Rescue's 2023 renovated adoption wing, which includes four group cat apartments and catios according to Peggy Adams Animal Rescue. The newest directly relevant veterinary guidance identified is FelineVMA's August 28, 2025 indoor-cat position statement. A September 2026 FelineVMA conference session is upcoming, but it is educational content—not evidence of a new product, approval, or housing rule.

What "cat apartment" means in practice
"cat apartment" is a descriptive term for a dedicated cat living or housing space. It is not currently a verified veterinary product category or recognized industry standard.
The Peggy Adams example involves shelter housing, not a universal design for homes. Its four group apartments and catios show one documented approach, but they do not establish that every cat benefits from shared apartment-style living.
What makes an indoor cat apartment suitable?
FelineVMA says indoor safety alone is insufficient. A suitable space must also support emotional and behavioral health in its August 28, 2025 position statement.
The guidance identifies several important features: This means size and appearance do not determine quality. A large, expensive, or attractive enclosure can still fail if one cat cannot withdraw, reach resources, or avoid unwanted contact.
- A safe retreat for each cat
- Key resources placed separately
- Opportunities for play and predatory behavior
- Predictable, positive human interaction
- Respect for each cat's sensory needs
What changes in a multi-cat home?
Multi-cat housing requires extra planning because cats may need distance from one another even when they generally get along. FelineVMA links better environmental support with less distress, fewer behavioral disorders, and less stress-related medical disease. Litter access is a practical test of whether the layout works.
Cornell advises one litter box per cat plus one extra, placed in multiple locations; cats that begin house-soiling should receive veterinary assessment because medical problems may not be obvious according to Cornell University College of Veterinary Medicine. A shared room should not force cats to pass one another to reach food, water, litter, resting areas, or exits. If one cat guards a doorway or resource, the apartment needs a layout change rather than simply more furniture.
Is there a legal size standard for cat apartments?
Federal enclosure rules do exist for regulated U.S. research, dealer, and exhibitor settings.
The e-CFR specifies requirements including at least 24 inches of height, 3 square feet for cats up to 8.8 pounds, 4 square feet for larger cats, compatible co-housing, litter, and elevated resting surfaces under the federal enclosure rule. Those requirements do not create a design standard for ordinary homes. Homeowners should treat them as a regulatory comparison, not as proof that a household enclosure is appropriate.
What is actually new in September 2026?
The next identified veterinary development is FelineVMA's September 24–27, 2026 conference, which schedules a session on adapting shelter-cat housing and enrichment for older cats in its conference program. The session may inform shelter practices, but it is not a launch of "Cat Apartments" or a new rule. For a home setup, check whether: A smaller arrangement that gives each cat reliable access and escape options may be safer than a larger shared room that creates competition.
- Every cat can retreat without being trapped or blocked.
- Food, water, litter, and resting areas are not concentrated in one contested location.
- The space offers play, climbing, elevated resting, and quiet sensory breaks.
- Any new urine or litter-box problem receives veterinary attention.
