He was skin and bones when he arrived at our house, his bones are not too obvious now because he is being fed regularly, but the last week he is eating like a horse and not gaining weight!Have you tried crushing one up an sprinkling on wet food?
There is a worming product available from French vets that comes in gel/cream form that I used to give to my cats but can’t remember what it’s called. It’s easy because you scruff them and then squirt it into their mouths. They can’t spit it out like a tablet so have to swallow it. It’s a bit expensive if I recall but, what you save on feeding a hungry cat, it’s worth it.
I expect you know this already, worming products are called vermifuge in France.

Actually, I recall using this too. I mixed it with some tuna and they ate it. It’s granules rather than a tablet.

Swaddle him firmly with a towel or a blanket making sure he can’t get any of his feet out. Hold him on his back like you would a baby, open his mouth with the hand that’s holding him and drop the tablet in with the other. Hold him until you’re sure he’s swallowed, massaging his mouth a bit if you think he’s holding on to it.
It’s the surest way because they don’t always eat it when it’s mixed with wet food even if you open a tin of tuna.
In fact they seem to have an uncanny ability to eat around any medication you try to hide in their food.
Open their mouth wide, get the tablet as far back in their throat as possible and the swallow reflex will do the rest (helped by massaging their throat a bit).
Towel etc a good idea but can sometimes be dispensed with depending on how much of a fight they put up.
Be prepared for dirty looks for several minutes afterwards but some of their favourite food can help mend the relationship.
You can get a special syringe that is made for tablets. Makes it easier to get it to the back of the throat without losing your hands.
It’s cots a couple of euros from the vets and works with all my 3, including the wild one.
I have also got a liquids syringe that squirts stuff down back of pup’s throat.
Use a spot on, I use it on our 9, I use Droncit for worms and frontline or beaphar for fleas it’s so much easier just apply to the back of the neck, I have used them for 15 years.
Just don’t use Bob Martens for anything 
Sorry, I couldn’t resist…

How To Give a Dog a Pill
Wrap it in a piece of bacon and toss it.
I love that it really makes me laugh I first came across it on the library of halexandria (halexandria.org) 
I first saw it about 15 years ago and I remember crying with laughter. 
And me…sooooooo funny 
Hilarious.
@anon88169868 Paul’s swaddle in towel upfront idea is looking more attractive now.
I can assure you that they can and do spit out even the gel - my fleece is a witness to my cat’s extreme dislike to the gel/cream
Oh dear!! I guess I was lucky that my cats accepted it then!!

Thank you all for your suggestions, the syringe method is the only one l have not tried and I will look at the drops option also.
I had bought several tablets from the vet (I should have asked her to administer 
) And it was becoming expensive! I normally leave my indoors cats’ left overs outside at night for another nervous stray and a hedgehog, so I also left the ‘doctored’ food out thinking Mr Ribs will eat it if he gets really hungry. Something/s are not so fussy and the dish is always empty in the morning! Could I be worming everyone but the one that needs it?
