I got one of my cats when she is already one year old. she is a spayed white Persian girl. The previous owner told me that she has been vaccinated. however, now I have some doubts about it. All of my other cats had been vaccinated except this one. and they are all indoor cats
she is healthy normally, however, I notice sometimes she had sign of cat flu. eg. she might start to sneeze a lot , for a few days, then back to normal.
sometimes , she will squint her left eyes for a few days, then back to normal again.
to me this looks like mild sign of cat flu. if she does have it, can I still vaccinate her? or she already has antibiotic inside her already, as she been exposed to the virus?
another reason I am worried about is, recently my other cat gave birth to 3 kittens. although kittens are very healthy and active, I did notice something , such as kitten squeeze now and then, they have a little bit black gunk under their eyes, not a lot, just a little bit. also one of kitten has teary eyes.
none of these are obvious, but there are mild signs, does that mean the kittens are already infected by this white girl? if yes,, can I still vaccinate the kittens?
btw, none of my other adults cats have these signs.
