hello,

i accidentally kicked the cat, and she hit her head on the metal frame
of our futon (i was getting up, and she thought i was heading for the
kitchen, as she always does, so i didn't see her when i took my first
step).  I didn't think anything of it, since she seemed ok, but there
was quite a bit of blood coming from her mouth, and a small cut on her
head.  the bleeding stopped after only a couple of minutes; i offered
her some treats, and she ate them all without any problem.  there is
however, some noticeable swelling, and she is a bit more distant than
normal.

is there a way i can tell if she is in pain, to the point that i
should take her to the vet? if she eats, and wags her tail, is this a
sign that she is ok?

thanks in advance for any responses....
