About 5 days ago I gave my cat some canned tuna fish (in brine) and I decided to add in it about a teaspoon of Cod Liver Oil which I bought from a pet shop store (of course I didn't know it could be so damaging on cats...furthermore, I bought this Cod Liver Oil from a petshop?!).
The day after the cat started vomiting badly and I also noticed some limping which I'd never noticed before...right now the cat has resumed eating normally and it appears as is a bit more mobile but not as before the poisoning.
As I find out more and more about vitamin A poisoning I feel more and more guilty - apparently the bone damage is irreversible...is there any remedy for giving back the mobility to my cat?
She's about 9 years old and very active and dynamic before the accident...only last week she would jump and chase led lights like a kitten and now she can't really be bothered.

Take your cat the vet.

Short post but true. I won't glaze over the fact that the cat needs to be seen....

I don't trust much my local vet - too long to explain why...I use it only for the yearly boost.
I have to find out another Vet and I need the time for it...

Definitely take her to the vets, I would be very surprised if its anything to do with the cod liver oil. Vitamin a toxicity usually accumulates over a period of weeks if not months of feeding high levels before it onsets. I suspect something else is going on here.

Hi and welcome

I imagine you are feeling quite concerned and is understandable you feel responsible in the way you do. Try to keep calm, if the cat seems to have resumed eating and seems fine within herself, hold out until you call the vet tomorrow, else for peace of mind, you could ring the emergency vet provision at the surgery where she's registered.

What happened might not be related to the teaspoon of cod liver oil and I would be surprised if that small amount would have such drastic effects as like what you may have picked up from reading when you got worried about her being sick and 'limping' the next day- our minds can play tricks on us when we are desperately trying to 'pin point' cause and effect especially when it is something we think we did or did not do to something/someone we hold dear to us. I hope the following acronym might help FEAR- false evidence appears real.

I hope I have not come across as invalidating the possibility of what could be serious, as I said is completely understandable your reaction, shows you care a lot about your fur baby.

Let us know how she is, I hope speaking to the vets will bring clarity and assurance to you. It's not your fault and I genuinely mean this

Deffo look for another one .

At 9 years old she's getting "close" to being elderly (if not already there) so it'd be good to rule out some other stuff too.

As someone else mentioned you could ring the emergency vets and they could advise you.

If the cat is still limping then I would suggest not waiting until tomorrow to be fair.

Agree completely. However, given the symptoms your cat does need to see a vet. A bloodtest would be a good idea.

Thank you all for your suggestions...

First of all, Baba (the cat in question) is getting better and better.
I think I was wrong into thinking that a teaspoon of cod liver oil could produce some violent vomiting not to mention the apparent stiffness in Baba....in fact, in the alley I found some red/brownish pellets of various sizes from 5 to 10mm with a black core which are probably meant to kill rats. I'd like to have a word with my neighbour about this accident - at least if they are concerned about rats they should use these pellets inside their own property - instead many of these were to be found scattered in the common area.
This is my hint anyhow...it's so difficult to spot exactly the reason why our pets get ill sometimes - not even sure if those pellets are rat killers (but I guess so).

I rang my vet and mentioned about this issue...still Baba is eating normally now and started chasing the led light and jumping as she normally does (not quiet there yet).
