First off, I am so glad that I found this forum. Secondly, I am a complete mess and need some help. I adopted my 2yr old cat, Lenny, from my boyfriend's old roommates, who sadly were extremely neglectful pet owners...like change the litter box every two months neglectful. It was so infuriating. I would step in whenever I was there and change his litter box, make sure he was fed. At one point, he was infested with fleas, and when they didn't do anything, I got him on a prescription flea medicine. Anyways, they called me exactly two weeks ago and told me that poor Lenny had been peeing blood for awhile. They went on to say that he'd been straining in the litter box for a couple months. They said they couldn't deal with it and asked me if I wanted him. WHAT?!?! I was furious that they had not taken him to the vet to see what was wrong and gef him some relief. I immediately said yes, and he was at my house the next day. That night I noticed he was crying when in the litter box, which they had failed to mention. The following morning I got him into the vet. After a urinalysis, bladder ultrasound, and an abdominal xray, he was diagnosed with a very large bladder stone. They got him into surgery the next day. This was so unexpected and my boyfriend and I were in no way prepared to pay $1500, but we did it, because Lenny is worth it. Fast forward a week, and I notice that Lenny is shaking his head pretty frequently. I'm not sure if he had done it previously, but I noticed it for the first time a week ago. I thought it could possibly be due to the fact that he had a collar on from surgery, so I waited until four days ago, when it was time to take the collar off, to see if he was still doing it. Unfortunately, he was. I got him into the vet again the next afternoon. I requested to see the owner of the practice. He told me that his ears looked fabulous, and that there was no sign of infection or ear mites. He asked me if he had been scratching them, and I told him I had seen him scratch them a few times. He told me that that wasn't a lot. I asked him if it could be an ear polyp, and he told me no, and that he would be able to see it. I asked him if he could always see polyps, and he said yes. He then told me if I'd like, he could send me home with some ear drops to help with itchiness...so I got those. $73 later, and I was back home with Lenny. He is still shaking his head. He does it mostly after stretching, when he first wakes up, after being petted, and after eating. I've never had a cat before, so I don't know if this could possibly be normal behavior. When my dog was doing this, along with spinning around in circles, he required major surgery for bulging ear drums. I'm so sorry this is so long, but I am a mess, and I wanted to give you all the back story. I am obsessing over the head shaking and reading every internet article known to man. I'm worried that my vet wouldn't have been able to see a polyp if it was on the other side of the ear drum. I read that that is a possibility, but that normally if it hasn't broken through the ear drum, it causes a head tilt, unequal pupil sizes, and loss of balance, which he does not have. Should I push for an xray? It says that sometimes in order to visualize behind the ear drum, that a CT scan is required. I don't have that kind of money right now. He's acting totally fine, but I can't stop worrying. What should I do? Does anyone have a car who shakes their head occasionally? Can it be normal? Thank you so much to those who actually got to the end of this novel.
