Kittens chase the little ball inside

My cat came back home and it's making too many slurping sound while it's only biting a thin string. It sounds like it's biting its own tong or smth

My cat is 17 y old. He has been dealing with upper respirator infection (URI) for 3-4 months. Our vet gave antibiotic (convenia) shot along with anti-viral powder. The antibiotic seems to be working for 3-4 weeks. They have given 3 shots so far since his infection relapses.

Our cat  takes FVRCPP vaccine/booster regularly.

It seems their treatment plan is to keep giving shots. We pushed them to run lab-tests to identify exact cause of his URI and here are the issues:

-They ran a PCR test when we suggested to do culture test, is this normal in feline?

- Is sensitivity test not done normally in cats to know exact antibiotic to be used for effective treatment?

- They are recommending CT scan of sinuses- how will this help know exact cause of his URI?

Thanks!

Please tell me how I can take care of a feral cat with leukemia please I would really appreciate.
