Yesterday she didn't eat anything and she was like gaging up foamy stuff, I just got up to check on her and she was in my closet laying by the water bowel, but I don't think she's been drinking, she came out into the Bedroom and stated gaging up some more foam, Thursday evening I gave her some cat grass she ate a bit of it, Could she have a hairball stuck she has a lot of hair and I do keep her groomed, she doesn't look right though, Not in a panic or anything just not quit right, is there anything I can do to find out if there is something stuck , plus I don't think she has gone poo for a couple of days I gave her the lthe stuff for hairballs 2 times yesterday ...
