My cats fit perfectly in XL and L, so I haven't used the red one at all. It makes grooming difficult, so we only put it on our cat when they sleep. When you put your hand on their back while they're wearing it, it's nice and warm. Red cat clothes made of fleece, cable knit design. - Color: Red - Material: Fleece - Design: Cable knit style - Size: M - Tags: PET Thank you for looking.
