Why is my Ragdoll cat shedding so much fur?
A Ragdoll cat shedding large patches of fur could be due to one of the following reasons:
1. Seasonal shedding: Ragdoll cats usually shed in the spring and fall, which is normal.
2. Malnutrition: If a Ragdoll cat's diet is unbalanced or lacks essential nutrients, it can also lead to hair loss. 
3. Diseases: Certain diseases (such as fungal infections, allergies, etc.) can also cause Ragdoll cats to lose hair.
If your Ragdoll cat is experiencing large patches of hair loss, it is recommended that you take it to a veterinarian for examination and diagnosis as soon as possible.
