worried mom

My cat is approximately & years old, female. Always an indoor cat until I recently moved and she took to the porch and the fenced in backyard. Last night she didn't come home, I wasn't worried because as of lately, she likes to go on adventures and slips under the fence. This morning I found her in a ball outside and she didn't run up to me. That's her norm. I grabbed a towel to bring her inside, and she is having trouble walking and cries if she tries to move around. I brought her some food, she heard me preparing it in the kitchen and jumped down from the bed, and immediately began to cry, even growl. I had to gently pick her up and put her on the bed, it's a futon and ow to the ground. She wanted her food but barely ate any of it, and when I looked her over she has two small wounds to her lower spine. Could these be snake bites? She isn't lethargic, panting, or foaming, just crying and apears to be stiff in the back when she tries to walk. Any ides? Comments? Anything to help?    

I'm sorry, Approximately 7 years old. 

Take her to the vet as soon as you can. Cats hide pain very well. If she's showing that much pain she's really suffering.

She needs to be seen by your vet ASAP...Could be a bite from any type pf animal..If it was another cat they can get infected quickly and will need antibiotics.

I hope you have managed to get your girl to a vet.  You must have been so worried when you found her and seeing her like that.
