No cat wants to be dirty, and it's up to you to ensure that your cat stays clean. Grooming is very important, as it helps your cat remain clean and healthy. Grooming starts with brushing, as brushing helps to keep the cats hair from becoming hairballs.
Even though you probably love your dog they may not love you during their bath time. Most dog owners will probably have to drag their dogs into the bath but after you read and find out more about bathing then maybe it won't be such a hard time.
