And that's why my cat is an outside cat who rarely comes in the house.

Cat: u mad bro? Trollolololol

Was the cat male? Was the cat's litterbox clean? If you answered yes to both, that's why the cat pissed on the bed.

I still love cats...even tho I Dnt have one :/

First, baking soda won't completely eliminate the smell. Get some Nature's Miracle, carried by most pet stores; it's enzymatic stuff for cleaning up pet messes, and works amazingly well. In general, a litter-trained cat will pee out of the box for only a few reasons: a health problem, a behavioral problem, or a protest. If this is an isolated incident, it's probably not health, but just in case, a vet visit is in order. The vet should be able to give suggestions for handling any behavioral problem, spay or neuter the cat if it's not yet fixed, or help diagnose what's being protested. Without more information, I'm going to guess the OP's cat was marking territory to try to reclaim the bed. My cat peed on my bed exactly once, when apartment maintenance people shut the door to her litterbox's room in the morning, then I didn't get home until late -- her protest was pretty clear. Some cats pee elsewhere if the box is too dirty; a regular cleaning schedule helps. If the cat doesn't like the girlfriend, having the girlfriend make nice to the cat could help, including having her feed it, give it treats, etc.

I love having my kitties sleep in my bed! If your cat is going outside the litter box, she might have a UTI. I'd get her looked at.

I've got 2 cats and both of them often sleep on my bed. They only do their business in the litter box. Even if they're outside, they go inside to do their business in the kitty litter. And to the people saying things like 'you should get a dog instead' , what would that solve? Dogs can pee/poo inside too and will also do that without proper training, just like cats.

Use vinegar on it, it neutralizes the ammonia smell.

And this is why dogs are better than cats. At least most dogs will let you know when they need to go.

Why would you even want pets sleeping with you? I'm sorry I love my dogs but they have their space in my house, it sure isn't in my bed.
