Well, about a year ago, my husband and I got this cute little black and white kitten because we love cats. Well, She always seemed to love playing, and never really liked to be held or petted.
She has never come to us for love, but we love an affectionate lap cat, so it's really disappointing. The only form of affection she gives is licking us, but she only does that if she just woke up, and we come to her.
Just so you know also, we take great care of her, we have spent almost $500 this past year on her for vet visits and meds because she's had UTI and Upper respiratory infection and we still buy this overpriced medicated food for UTI in cats..
We have always put up with her independent attitude, even though we'd prefer her to be a bit more loving. But in the last few months, she has gotten pretty much unbearable. She loves to howl at the top of her lungs all the time! We've taken her to the vet several times, where they have tested her for any sickness that would make her do that, but she is perfectly healthy. We tried giving her loving attention (which she will literally hiss at you if you do!), playing with her, and feeding her to make it stop, but she continues the second you stop. For the last month, we have completely ignored her howls, despite how loud they can be, or how they wake us up all night. So, it's really making our sleep suffer.
She's also always been a playful biter / scratcher. She never really left marks, and we would walk away and ignore her when she started to. Now, for the past 3-4 months or so, she's a lot bigger, and the behavior hasn't changed. If you go to pet her after she wakes up there's a good chance instead of licking you, she will immediately latch herself on your arm and MAUL your hand!! It goes from possible sweet licks to mauling in .01 seconds! I have scars and awful bloody scratches all over my arms and now legs.
She has gone from being sweet 5% of the time to .5%, and frankly, we feel like she doesn't even like us at all anymore!
I really hate to say it, but I don't want a cat like this anymore! We've tried to put up with it the best we can, but we aren't getting anything out of it! I understand you shouldn't really have expectations of animals, but this is ridiculous!
I really hesitate bringing her to a shelter, because she's not a kitten, and she's completely rude, so I really don't think anyone will want her.. I don't know what to do! Someone please help!

Have you thought about getting a second cat? She may be bored despite the attention she gets.

We have thought about it some.. It would be a few more months before we could do it, but that;s what we might have to do.

I see 2 separate issues: one is that you don't train a pet by 'ignore and walk away.' My kitten bit and scratched and it was imperative that it stop because of my elderly dad's medical problems. It took 2 days of loud sharp NOs and a quick gentle whack. She stopped.

A NO is not accompanied by any other words and it must be loud and short.

The second is yowling. To my mind that means PAIN (if not in heat). I think the vet missed something.

If the cat was somewhat feral she might never socialize with people.
I have friends who were given a kitten born to a feral mother, and it grew up totally deranged, viciously attacking people with no warning and being totally anti-social. Their vet said the mother probably had distemper.

It's OK to find the cat a new home, even if that means taking her to a shelter. JMHO.
