How can I tell if a grey cat is a true small breed or just a color variation?
Look at body proportions, head shape, ear set and coat texture in addition to color; true breeds tend to have consistent physical traits and temperament, while color variants appear across many mixed cats. Checking pedigree papers or consulting a breed club or vet can confirm breed status.
Which small grey breeds are easiest to keep in an apartment?
Choose by temperament and maintenance: calm, low-activity breeds that tolerate indoor life (for example, Russian Blue or Chartreux) are good fits, while hairless types like the Sphynx need more bathing. Prioritize compatibility with your schedule, grooming willingness, and allergy considerations.
