Das bin ich:

 Lia, female, 7 years old, spayed, single cat. 
She was taken from my neighbourhood for spaying. She also had breathing issues - that is why she is shaved on the belly that much, for medical check up. She received mycoplasma and lungworms treatment. Her breathing is better now.

She is dominant and beats other cats badly. That is why she sometimes has to be separated in a cage, until she calms down.
