Cat is limping.. what could be wrong?

[Ryan]

Our cat has been limping for 2days now.
Everytime we touch her paw it trembles and she meows and hisses and freaks out.
But this is normal behaviour for her (the meowing and the hissing) shes abit of a sour puss.
We checked out her paw and she still has all her claws in tact and has no marks or scratches.
We didnt have time to check if her paw was swollen.
What do you think is wrong?

She could have gotten into a fight or something. If you wait a few days and are still worried you should take her to a vet.

maybe she can't clean her back side, properly has dyed poop on the back
check if she has dyed poop. if so, give her a bath, our cat does this too so we give her a bath
