Hi... I have the same problem with my 4!
Its pro pet salon by 8 in 1 products... http://www.eightinonepet.com
Pro Pet Salon Detangling and Freshening Spray - For Cats
Extra-mild freshening formula contains aloe vera and unique coat conditioners to help detangle mats and tangles. Gentle enough for daily use. Baby powder fragrance.
This sounds similar:
Petsafe Anti-Tangle Spray 4415
Pamper your pooch from head to foot with this specially formulated spray from Petsafe £2.99
PS... scamps a cutie!
I think Johnsons also do something called 'groom spray' or something like that which is for puppies but it ok to use for cats.
