Help, my cat cannot keep any food down but treats!

My cat, who is 13-14 at age has a blockage in her intestines.

When she eats her normal cat food, she pukes it up.

When she eats a small handful of treats, she keeps it down.

She is already a little pork-chop with my dad feeding her every-time

she meows at him, so this is not good. She barely moves

from this one corner. We don't know what to do, ideas?

I'm a little confused. Did a vet diagnose an intestinal blockage but not suggest a treatment?

I was also going to ask about the vet. If your cat has not been to a vet yet, he needs to be seen ASAP.

Yes, I'm also confused. I don't think she would be able to keep anything down if it were a blockage. She'd need immediate medical attention. 

My dad said there was a blockage, she can only digest small ammounts of food.

My mom wants to wait, as she is not choking, sufficating, or dying.

She seems fine, she just wont eat..

Although, it might be that fried spam I gave her

on Saturday.. My parents told me not to give it to

her after she wasn't eating.

She just sat there and slept all day..

I can only repeat that if your cat has not been to a vet, your cat needs to be seen by a vet.

Ooh, hey! She is in the kitchen asking for food! brb..

Ok, fed her. My mom says my dad is just worried

and she might have pasted the blockage.

We are going to see how she does tonight...

My mom says if she will STILL not eat, then she will be taken to the vet.

Okay first of all please please please do not give your cat FRIED SPAM! Ugh. That's just so wrong and bad for her. And secondly, how on earth would your dad know she has a blockage? Only an x-ray or ultrasound from a vet can diagnose this. I really don't understand any of this but I wish you would take this cat to the vet. This can be extremely dangerous and not eating is just as dangerous. It takes less than 48 hours for a cat to develop fatty liver disease from not eating the proper amount of calories. 

Okay, okay... She is eating now, I want to wait.
 

I just talked to my parents, we are taking her to the vet tomorrow. I hope she is okay..
 

what did the vet say? Did she xrays done?
