My outdoor cat is itching and biting. Could it be fleas or allergies?

Pet's info: Cat | Maine Coon | Female | spayed | 3 years and 5 months old | 12 lbs

Hi my cat has been scratching and biting herself in the same spots for about a couple weeks now and i thought it was just the weather changes but I'm starting to wonder if she might have worms or fleas? I haven't noticed any jumping off her and i have been checking her poop and pee regularly and nothing. She does go outdoors alot but im usually out watching her. Any ideas? I have no pictures to show.

I am sorry to hear about Jewel. Fleas are definitely a possibility in any pet who is itching, even if they are supervised when outdoors, a flea can easily jump onto a pet without our notice. They can also be very difficult to find on a pet if there are just one or two fleas. In addition, some pets are very sensitive to flea bites and just one or two bites can make a pet very itchy. Other possible causes could include allergies to things in the environment such as grasses/pollens/dust. If your kitty has red lesions/spots/scabs/bald patches on the skin I would recommend an examination by your vet. If you don't see any skin lesions you could try using a flea preventative (your vet carries several types such as Comfortis, Bravecto, Revolution or you can purchase a product such as Advantage or Frontline at the pet store- be sure to purchase a product specifically for cats). You can also try a fatty acid supplement which can decrease inflammation in the skin, such as Cutaneo trubenefits which you can purchase online at: http://www.vrshealth.com/feline-products/?petcoach=1977956 If the itching persists or skin lesions develop then a vet exam is needed.
