I always give Rosie a wormng tablet every 3 mth.

Do i need to seeing she's an indoor cat?

Generally once they get the series of dewormers as a kitten, or stray they don't need regular worming if indoor only. The most common worms found in indoor only cats are tapeworms which are contracted from ingesting an infected flea.

Thanks for that. I didn't think she did but thought i'd check.
