The bit of reading I've just done, it's suggested that whisker loss can
happen as a result of stress or as a reaction to antibiotics.

Ask your vet if he/she has any ideas about this.

Just out of curiosity do you have another cat?  The reason I ask is
that...........

I have a cat who has the same thing occur.  I was in a panic when I noticed
it the first time because she also had a leg amputated due to a fast growing
giant cell tumor.  My first thoughts were something was wrong and possibly
cancer again.

After 3 days of constant worry and waiting for a vet appointment I found out
the culprit.  It turns out my oldest chews her whiskers off.    He's been
doing this since about 6 months after her amputation and he keeps the side
with the leg amputated trimmed back to about an inch.  It's not like they
don't grow out and are shorter than the other side because of the leg loss
already but for some reason he trims these and she lets him do it.  I don't
know if he thinks they are kitty dental floss or if he's concerned she'll
get herself stuck somewhere.

Some cats shed whiskers more frequently during change of seasons.  I
wouldn't worry too much about it unless is becomes excessive.
