My cat have its first bath on 7/8 ever since he stayed with us at 4 months old. It is now 2 months to 1 age.
The most surprising thing is that after the bath, it became not naughty as before. It still likes to play though. How perfect it is and I like to touch or hug the cat more often as it feels so clean and refreshing.
I will give it bath whenever its hair became sticky.
Happy Cat / Happy Life!
