Cat is disoriented, walking funny, staring at ground

My cat Harley is about 1 year 6 months. She was completely fine last night before going to sleep. I woke up and she was meowing constantly, her meow was pretty raspy. It sounded like she was thirsty so I directed her to the water, but she wouldnt drink it. I also tried giving her food, she seemed interested in it at first, but wouldnt eat it. Shes pretty disoriented, shes not walking the right way. She keeps just laying on the ground, and staring at the floor. And if you look at her or touch her, she acts as if you scared her, even if she's looking right at you. Someone please help, if you have any advice. This is my baby and I cant lose her

Also. She was acting this way a few months ago, when we allowed her to go outside. We took her to the vet and they thought she may have got into something toxic. They said her body temperature was dropping and that she was trying to pass away. Miraculously, she pulled through. But ever since then we haven't been letting her out unless shes in our sight.

I am glad to hear your baby is doing better.  Many years ago when I was a kid my family's cat was indoor outdoor. She drank some anti-freeze that was leaking from a neighbors car.  My parents rushed her to the vet for the same symptoms you are describing.  She went on to live a long life. I am glad you took your baby to the vet and she is doing better.  Our neighbor discovered the leak in his car the while my dad and I were at the vets with the cat.  My mom called the vet's office to let them know.  Our neighbor felt bad for not noticing the leak and insisted on paying my parents for the vet bill.
