My rescue cat is COVERED in matts. they are just terrible. i've tried everything to try and loosen them, and nothings working. so i've decided i'm going to shave him. (poor cat...he's gonna be the laughing stock of the town!) i'm just not sure when to do it. he's an outdoor cat, and i don't want him to be too cold. its been around 50-60. and this week its suppossed to get up to 70. i can tell his matts are really uncomfortable for him and i want him to feel better and get him shaved asap. is now a good time? he doesn't stay out at night. only during the day.
