Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to spoil your cat [title] Develop a brushing ritual with your cat. [step] Your cat will love the rhythmic, front-to-back motion of you brushing her coat. In addition to being a way to spoil your cat, brushing her coat serves several practical purposes: stimulating her skin, cleaning her fur, spreading natural oils throughout her coat, and preventing tangles.

Ending1: Start by practicing a brushing routine every day. This will help to keep her hair cut short and shed dead skin. Ending2: [substeps] Choose a brush that is cotton-based or wool-based. Non-cotton bristles may be easier to clean, as they are hard to remove and are generally less likely to leave streaks or marks than other brush brushes. Ending3: [substeps] If you have never brushed your cat before, keep the first session short (5 to 10 minutes). You can lengthen the amount of time as she becomes more comfortable with you brushing her. Ending4: [substeps] Brush your cat's fur under her chin. This is particularly important for aging cats, as the hair growth is now dying and you need to keep her looking healthy and supple.
