yeah i heard abt that, a bit pricey but do a good job they say. so i have to choose between that and Advantage Spot On because Advantage got a lil bit discounted price. I heard abt this Advantage from a community who are catlovers in Facebook that I joined for quite some time. So i gave it a try for that.
If anything fails, then I ought to get that Frontline Combo for cats. Im having a hard time though for not letting them licking each other...they love to lick each other     

have you had tried those homemade fleas killer...?? have u any experience on that? they say using apple cider vinegar is quite good, even the cats can lick it off but i know the smell is quite off putting..

i am a little frustrated.

I have a female cat about 2.5 years old. She is very well behaved and I think we bonded pretty well.

She will answer and approach you when you call her name. She understands enough to stop doing something when I yell out "no" even from a distance, without having to walk to her. She plays fetch and gets in a "ready to fetch" stance if I say "do you want to play fetch?" before I even get the ball to throw. Very vocal and she will carry her toys to you when she wants you to play with her.

The thing is, in the past month she had been peeing outside the litter box. on the floor, on her cat bed (so far i've thrown away two cat beds), and the last incident and most frustrating was on the bed (other side of the bed, not the side i was sleeping on). She never done this in the other 2.5 years growing up with me.

I understand there are two possibilities. Behavioral issue or medical issue.
What I don't understand is that why would she has behavioral issue when there is no change around the house. we didnt move house, no furniture change, no furniture move, no new bed sheet, no new person, no unfamiliar guests, no new pet, i never even change my dishwasher soap brand (not relevant, just showing that I am a pretty consistent person).
I also try to check out medical issue but vet said she seemed fine and he touched the bladders and he confirmed theyre soft and didnt feel like there's anything wrong. she is now being put under medication plus antibiotics for few days to see if it improves and vet also suggested to do lab check to test for infection after a week or so.

She doesnt seem to be sick though.. She's still very active. Play all day, jumps, runs,talks, eats and drinks aplenty.

Does anyone have any idea or advice?
