What is the ideal weight for a Ragdoll cat?

Healthy adult Ragdolls typically weigh 4.5-9 kg (10-20 lb), with females usually toward the lower end and larger males toward the upper end. Weight should always be assessed alongside body condition score rather than as a standalone number.

My Ragdoll weighs 8 kg -- is that too heavy?

Not necessarily. A large, well-muscled male Ragdoll can healthily reach 7-9 kg. The key is body condition: can you feel his ribs with light pressure? Does he have a visible waist? If yes, his weight is likely appropriate. If his ribs are hard to find and his abdomen is round and soft, he may be overweight regardless of the number on the scale.

Does the Ragdoll's thick coat make it hard to assess body condition?

Yes -- that's why BCS should always be assessed by feel rather than by looking at the cat. Part the fur along the ribcage and feel with your fingertips. The cat should feel muscular and firm, not padded with a soft, squishy layer over the ribs.
