You can give them kitty treats especially formulated for hairballs. My kitty actually likes these, but he's already over 20 pounds and the recommended dosage is 5 treats a day.
There are even some home remedies that you can use and you most likely already have it in your pantry.
- Butter - add 1/2 teaspoon to food once a week
- Olive Oil - add 1/2 teaspoon to food once a week
- Petroleum Jelly - place a dab on kitties nose and he will lick it off. The jelly will smooth the animal's digestive tract and allow the hair to glide along smoothly.
I bought a Furminator and it's really helped get that thick undercoat out. Amazon has some great deals on this tool, you just have to watch for it.
Hope this helps you keep your
kitties happy and healthy!
