<human>: Can you succinctly summarize the text in 1-3 sentences?

Just hoping to get some advice from strangers on the internet because I can't make a decision about this.

My cat whom I've had and loved for the past 3+ years will throw a tantrum every few months. He will throw up on his bed and then wait for me to clean the cover and put it back on before immediately throwing up on it again. He's at a very good weight and I rarely change his food type or amount. He also urinates on everything I love during these times.

It's been okay before this year because the pleasure of owning my cat has made it worthwhile although I've never discovered the reason for his tantrums (I've been to the vet so many times over this. They always check him for a uninary infection, find nothing, and send me on my way with a big bill).

This year however, my college classes have been getting really difficult and I've had some pretty significant health problems. I feel like I'm at the end of my rope here. Plus I'm trying to move across the country next year and I know the trip will be traumatic for him.

I don't know any of my friends or family who would want to take him, plus I wouldn't want to make him a burden to someone else. I can't justifiy giving him to a shelter to be adopted by someone I don't know or spend the rest of his life in a cage.

Any advice?
<bot>: My cat pukes and pisses on my things every fews months for years now. Due to health and school stresses, I can't keep up anymore.
