Why is my kitten no longer jumping? Climbing?

Some quick backstory, my 15 wk old kitten reacted very badly to his (what I feel was an "extra", unneeded) 4th fvrcp booster 9 days ago. He took 3 days to rebound from that and finally become his old playful self. But since then, he's been tapering down on his energy level. He used to chase the laser all over the place and jump and follow it, whenever and wherever. Now, when it gets to the couch or the cat tree, he sits and watches it and doesn't jump up to "get it". He used to also climb his cat tree with a passion, racing up and down, but not recently (the last maybe 4 days).

He also pees a lot (now 9-11x/day and twice outside the box) and we're investigating that. I took in a free catch sample yesterday, results due back tomorrow. He had a needle sample taken at the appt the vaccine booster was given (which is why I don't think he should have been given shot when he's clearly not 100%), and the vet called and said that it was free of crystals and she said, infection. But I've read that sometimes infection lower in the urinary tract isn't picked up thru a cystocentesis. He's had boodwork done and a fecal sample done, too. Vet said those were clear and neg.

Could a UTI cause a slowing down of energy level? Is it causing pain to jump? SOMEtimes he can still work up enough energy to chase his favorite cat dancer toy but he doesn't chase the little balls and toy fish/mice/etc. that he used to and the not climbing and playing on the cat tree has me worried, esp when it's to chase the laser up the cat tree. He just sits and stares at it going up the tree, as if thinking, "I'll just have to sit this one out, because I'm not up to it."

Or could a problem with his kidneys be causing him pain/fatigue in his hind quarters causing it to be difficult or overly taxing to jump and climb?

Thanks to all!

p.s. Has anyone heard of it being bad to give a fvrcp booster to a cat with a UTI? Kidney issues? I just read a post from another member that said his kitten almost died from acute renal failure from a fvrcp booster....absolutely tragic and frightening

I guess these extra boosters are a new thing, because when I last had kittens, they got their first shots, then one set of boosters, and that was all, so a 4th set must mean there was also a 3rd set too.   Mine are 6 1/2 YEARS old now though, so things may have changed greatly.   

I don't have any answers for you at this point on any of your questions, except that I would definitely think a UTI would cause a slow down, just like it would you or I.  I would NOT think it would effect whether or not a cat could climb or jump though.  

Have you gotten the results of the free catch yet? 

I have found that my cats figured out really early on about that laser.  Since they could never catch it, they lost interest in it.  I even tried putting treats around the house and then there would be something at the "end" of the laser hunt, but that didn't really work for them either.   And sometimes they just don't want to play.  You know cats, they have their own schedule.

I really doubt it is anything to do with the 4th vaccine, kidneys or a uti actually.

He's awfully young for kidney issues or a uti, this is generally seen in cats older than he is. If he is peeing more, he is drinking more. 

It's peeing less that would be worrisome.

What is his history, where did you get him from, how old was he, etc?

Shelter? Born to a feral?

Has he ever had a cold/URI?

Tested for felv?

@mrsgreenjeens  yes, lol that must be it! I bet Boone has figured out why jump up on the wall and put out the effort to get the phantom laser? Cats sure are smart and fickle.  And yes, there was a 3rd booster shot. I spoke to the vet on the phone just now and she gave me the results from the free catch. She said that it came back negative. She said that the next step would be performing an ultrasound on his bladder to look for a bladder abnormality, which she admitted would be rare, but she said all the tests are not pointing to diabetes, kidney disease or UTI...I'm so baffled. I thought him peeing outside the box definitely meant he had a UTI, but she said no.

Do you think asking to treat for a UTI with antibiotics just to be on the safe side would be prudent/safe or over-doing it at this point? The other vet at the other pet hospital which gave him that 4th fvrcp was saying they could give him a broad-spectrum antibiotic to be safe, but then again, this is the place who gave him the vaccine when he wasn't 100%, so maybe they're just treatment-happy?? Sorry to have so many follow-up questions, I just don't understand why a) Boone pees SO much (in the last 12 hrs he's peed 6x) and b) why he doesn't self-play and jump up/climb the cat tree as much anymore, has less energy than before the booster

@catwoman707  I understand what you're saying that if he's peeing a lot, he must be drinking a lot, but where is he getting the water? He IS on a wet-only diet, but I NEVER see him drink. I bought a cat fountain thinking maybe I could entice him to drink from that, but I never see him drink from there either. And I'm home a lot recently. Maybe he's drinking from the drippy hot water faucet in the bathroom sink? But that's hot water! Would he drink that? I've never seen him, but that's the only other place I can think he'd be able to get water. I keep the toilet lid down.

I adopted him when he was 9 wks old from the SPCA. I don't know his history unfortunately. But he'd been there at least since his first fvrcp shot which was given it appears when he was 5 or 5.5 wks old, from their records. I don't think he's ever had a cold. Just that terrible reaction to the 4th fvrcp shot. He was fine after the 3rd. He's not been tested for FIV or FeLV yet as he's not 16 wks old yet. He is due for his rabies and FeLV test this week, but I am EXTREMELY hesitant to give him the rabies shot yet until we get to the bottom of all this and I don't want him to have a horrible reaction like with the 4th fvrcp....  

I would personally hold off on the rabies vacs for now.

No, I do not think he should be given broad spec antibiotics or any other ones unless he has a blood panel done that clearly shows elevated white blood cells, which means an infection somewhere.

However his appetite is still the same?

Canned food is loaded with water, and often cats will rarely be seen drinking, but it's coming from somewhere to be expelled, so the canned must give him plenty.

Are his pee balls smaller or ?? 

Generally speaking kittens so young just don't get uti's or bladder infections, not impossible I suppose but gosh, that's something I literally never see with my rescue group fosters.

On occasion an adult might but never kittens.

I did want to be honest that I asked about the uri status in case he is in the early stages of fip.

I would want him tested for felv though. It's highly unlikely, and VERY rare for a kitten to have fiv from mom, but they can be born with felv if mom had it.

Also, whatever you are thinking happened after the 4th vaccine is extremely unlikely, he would have reacted prior from one at the time.

It's not considered overvaccinating by him getting 4, in fact in Michigan that's standard, 4 rather than 3 as we in CA do.

UC Davis Medical Teaching school Dr. Kate Hurley who is an acquaintance of mine now, her and her crew just came and spent 1/2 day at our humane society to asess it and give recommendations.

During this when we all sat in a meeting after their tour, I was shocked to hear that shelter kittens will often receive vaccines every 2 weeks as long as they continue to be residents of the shelter for up to 8 times!! Yeah, that was very surprising, and honestly I wouldn't do it, but just goes to show you that kitten's getting a 4th is not going to be harmful.

I would say there is something else wrong, just not sure what it is.

I would want to rule out felv, as well as fip though at this time.

I agree on not just arbitrarily giving an antibiotic.  Kind of like with people,I think  taking them too often can cause issues when you really need them 

thank you to you who have posted replies!!

@catwoman707  I agree, I'm going to hold off on the rabies vaccine until I get a better handle on what's going on...do you know how long I can wait to do the rabies vaccine? I have no idea what the law is. I just know I'm supposed to vaccinate in the state of CA. Ok, the consensus here seems to be to not give antibiotics, so I will not allow that to happen unless I see clinical evidence that deems it necessary. His bloodwork was fine re. WBC. Yes, his appetite is normal. He eats 3-4x/day. Sometimes his pee balls are on the smallish size, but more often than not, they're normal and a couple are always huge. I will most definitely test him for FeLV and is there a test for FIP?

No test for FIP.   And this is one diagnosis you do NOT want to get .     Strictly diagnosed by symptoms, which is sometimes incorrect. 

They can however do a titer test to determine if he has ever been exposed to the coronavirus, which is where FIP mutates from.

If the test is negative, then fip can be ruled out, if it is positive it is not a diagnosis of fip, but only that the chance remains open as a possibility.

So I would get that as well as an felv test.

Don't bother with an fiv test, in the very rare chance that he was positive for that, it wouldn't be showing signs already anyhow.

FIP and FELV it can.
