Why is my 11-month-old female cat meowing loudly? Is she in heat?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach!
Starting her heat cycle in a unspayed female cat is the most common reason for increased vocalization. Other possible causes are: she sees other cats outside (territorial), anxiety (cats outside, starting heat, changes to house hold), attention seeking, or medical issue.
I would close the blinds temporarily, provide environmental enrichment (cat trees, interactive cat toys, lazer pointer, play with her) and consider spaying her. You can also consider a Vet exam to be sure it isn't a medical condition. If she is otherwise fine, I hope that is improves with time and some of the above.
Have a great day!
