Well, we had many weeks of one or both of our cats being sick, at least once a week. One week was horrific, I think it’s called regurgitation where a long line of the food that sits in their oesophagus comes back up, I’ve never seen anything like it, a column of about 10-15 inches of undigested food culminating in a load of fur at the end.
Anyway, I’ve started brushing them more frequently, at least twice a week and so far neither has been ill. Hopefully this along with anti fur ball treats should be enough to keep the now reduced amount of fur passing through them. They are indoor cats and many outdoor cats have the luxury of bushes and undergrowth pulling a lot of the loose fur out.
