The quick answer
Indoor light and temperature can blur seasonal shedding patterns, while warm dry air loosens coat.
What to check first
Compare coat density, skin condition, grooming, diet and whether loss is even on both sides.
Why the details matter
Timing, frequency, body language, appetite, mobility, grooming and litter habits can separate an ordinary preference from a meaningful change.
What to do now
Brush little and often, clean loose fur and keep nutrition complete and balanced.
Make the change cat-friendly
Keep the routine predictable, preserve an easy exit and introduce only one safe adjustment at a time so you can see what helps.
When to contact a veterinarian
Bald patches, inflamed skin, weight change or intense grooming needs veterinary care.
What to record
Note when it began, how often it happens and what occurs immediately before and after. Photos or a short video can help show change over time.
The practical takeaway
Start here: Brush little and often, clean loose fur and keep nutrition complete and balanced. Follow the warning guidance when the pattern is sudden, persistent or paired with illness signs.
