Worried about my cat

Question
My cat is about 7 yrs old and is spade. She was fine yesterday but when i came home from work last night she didn't seem herself. She was laying down and meowing in one position and looking into space. she wouldn't get up at all, finally she did and was walking really slow. Her tail was down but flickering at the end but she started to vomit clear liquid and was drooling a slimy white substance.

Today she is doing the same but is throwing up a yellow substance, she will drink water but won't eat. She will also purr when patted and will rise her behind as you pat her back end. She will lay in the most awkward places and her tail is now all puffed up. What could be the problem?

Answer
Philippe,

Remember, I am not a vet, but, you must get your cat into your vet immediately.  It could be that the cat got into something or has some kind of nasty infection.  In any case, this cat needs veterinary treatment as soon as you can.

Please let me know what your vet finds.

Best regards... Norm.
