My cat gets pretty fractious after being in a closed space for a long period. I've had to drop him off earlier than his appointment time three times now.
They never seem phased by his behavior and tell me I don't need to apologize. (But I do, lol)
After the full coat grooming, my cat comes back smelling sooo good (I literally just hold and sniff him for the following days), his nails trimmed to a good length and fur so soft.
Most importantly, the cat seems pretty proud of himself when he gets home.
Your kittenhead will be in good hands here!
