This is my deaf cat Milla. I've got her from an animal protection organisation:
http://katzenhilfegraz.at/
She was born deaf because of a genetic defect which is quite common in many white animals cats, dogs, horses...
Because many have asked in the comment section she is perfectly fine, she did NOT have her vocal cords removed xD and she CAN meow she just did not WANT to in that specific situation.
The noise she's making is called chuffing or chattering cats produce this sound when they see prey they cannot reach. Perfectly normal and natural. :)
And for all you you, who don't believe that Milla can meow, wath this
• Good Morning, Milla.
