I am glad to see that others have commented on the dangers of eating string. It is very often a fatal mistake - http://www.associatedcontent.com/art...mbination.html - a ball of wall and a cat should never be left alone together either.

Also, I thought my cat was just simply catarwhauling but it turns out that can be a symptom of thyroid problems, especially in older cats, so you may want to run a bloodtest.

Stay safe.
