Yes, it was your topic I saw.
Tommie does swallow a lot, especially when he's purring. He swallows a few times and then coughs. Just as if the purring irritates his throat.
I don't think it's herpes though, because my cats never go outside (we live in an apartment building) and are never in touch with other cats. And feline herpes is very contagious, and our other 2 cats don't have any problems. And he doesn't sneeze or anything and it seems to be chronic.
And no, nothing stressfull happened lately. Although he's a bit of a stress-cat by nature.
Maybe I should film it or something
