cat sick or flees?
I have a 1 year old female (spayed) indoor cat (she goes outside maybe for 40mins per week while we are watching her). Recently she has been really bothered by something but all of the sudden. For example: her back leg will start shaking very fast and then she will move, and furoushously lick herself. Or her back will quiver and then she'll run and start licking herself - she seems very bothered when these things happen. It happened one evening and bothered her off and on for an hour, then it was fine for 3-4days now its doing it again this evening... she also seems a little more tired than normal. Also she does wear a flee colar, I put it on after the first incident.
Anyone have any ideas, should I take her to the vet?
