Fitting cat post feeding

The cat falls on side and regularly urinates himself. But also has aggression episodes. Owner not being helpful with recording the episodes, might get lucky after the fifth talk with her.

Here are the original fasted blood results:

alt 97 (30-60)
alb 33 (23-36)
alkp 202 (7-75)
urea 10 (3.5-8.0)
crea 151 (40-180)

bile acid fasting 2.8 (0-40)

And the post feeding ones:

bile acid 2.0 (post feeding) (0-50)

This cat needs sedating for bloods as a bit feral and bile acids not taken on same day

Similar case from a feline colleague on feline forum- copied and pasted-

"Once I had a 2 year old cat who was literally throwing himself onto walls after each meal.

Seen by two other colleagues before me, both treated for epileptical seizures, but really no improvement with phenobarbital and painkillers.

I also had no clue, blood was perfect, and I made X-rays not really knowing why and what I really was looking for...

And surprise, there was a white dense spot in the liver-stomach area, gallbladder stone maybe ?? Was really strange in shape and localisation...still no clue of what it could be.

Ex. laparatomy : foreign body in the stomach, it was a tiny Barbie doll plastic boot that became so hard with the stomach acids that this poor cat was driven crazy by pain each time he was eating....."

Another comment from a feline specialist echo's Andrews post that if bile acids are really normal, then its not a shunt. Also that with shunts, you wouldn't tend to get an instant post feeding aggression and then full recovery, more likely to have some behavioural change which may include aggression, followed by dullness and lethargy.

I think you need to visualise what this cat is doing, consider abdominal imaging, dental assessment under ga if nec and dental xrays, a pain relief trial if they don't want to do anything else.

You say its stunted- is it just small or underweight?

Post full bloods if you can

[quote user="dachsie_4"]

Has anyone experienced a burmese cat having fits (ranging from mild to severe aggression) post feeding???? This is a stunted burmese that was found as a stray 2 years ago. Was castrated then, no fits. Now started having fits often post feeding since a change of diets to a more expensive cat food 2 months ago. Full bloods run including bile acid stim and the pathologist from lab promised me that with blood results like I've got it's definitely NOT a liver shunt. So by all intense as purpose we are not looking at diet and doing a diet trial. But I have warned owner might be a problem in the brain. But the owners insist it's mainly after feeding. Any one seen this before???

Not something I've seen before, but I wondered how soon after feeding the fits are happening?

I disagree that ammonia is likely to be helpful here, its a difficult test to run and the sensitivity for PSS is lower than bile acids, so I agree that if a bile acid stimulation test is performed correctly (and the major reason for spurious results is if its not performed correctly) and submitted to an external lab then you can exclude a shunt more reliably than with ammonia testing.

It might be useful to see the actual results if possible?

I would agree with Martin; until an ammonia has been run it's hard to definitely rule out a shunt. Even an ultrasound scan might miss a small one.

[quote user="Utlendigur"]Just wondering given that it's a Burmese and associated with feeding whether it could be episodes of orofacial pain syndrome? They can lick their lips and paw at their faces extremely violently which could mimic a seizure[/quote]

That's a really good call

Also, are they definitely fits? Just wondering given that it's a Burmese and associated with feeding whether it could be episodes of orofacial pain syndrome? They can lick their lips and paw at their faces extremely violently which could mimic a seizure

Two possibilities spring to mind - it could be a shunt that the bloods haven't highlighted. I'd consider repeating the bloods or, as Martin has said, do different tests to rule in/out.

Or it could be the owner is wrong about the timing, you've said they told you it's 'mainly' related to feeding. It's amazing how mistaken we can be when we want to confirm something we believe to be true. You could ask them to keep a precise diary of times of feeding and times of siezures. How often is it being fed? If it has half a dozen little meals a day chances are that any untoward event will happen not too long after eating!

[quote user="dachsie_4"] it's definitely NOT a liver shunt.[/quote]Still sounds most likely to me. I would want imaging and post prandial ammonia which is not practical outside a referral practice lab. We had a similar situation in a kitten but it was only a few weeks old. They could never rule a shunt out or in from blood tests and it was too small to reliably image. There was some stuff about storage enzyme disorders but I can't recall enough about the case to look up the clinical notes (if I remember I will). Anyway the bottom line was that it was controlled by giving antibiotics and lactulose, we didn't want to go low protein diet because it was a kitten but that may be suitable for your case especially as you say it started after changing to a 'more expensive' i.e. possibly higher protein diet. Bottom line is, if its not a shunt its something weird that needs further investigation.

Weird. Thought this MUST be a shunt until I got halfway through your post! Am afraid I have more questions than answers at this stage!

Were there any abnormalities on bloods at all?

Is owner with cat all day? Can she be certain it isn't having fits at other times? Have you seen any video? Are you sure they are fits?

As I type I'm thinking could this be extreme post prandial pain?
