My 5 month old cat has been acting strange since yesterday, I found her with blood on her mouth and her fur is dirtier that normal, and her face smells really really bad, also her mouth is like shivering almost, like shaking? I don’t know how to explain it.
This could also account for the shaking, since fleas are literally blood sucking parasites. Again, all of these things should be able to be readily ruled out by a veterinarian, so I encourage you to setup an appointment as soon as possible.
