I have two persian cats and use this regulalry when they are moulting. It really helps reduce sickness and hairballs when things are bad. They love the taste so much I actually use it as a treat for them!
Katalax paste is very effective and very palatable for all my cats. Even the fussiest will have a chomp on this. I use between half-an-inch to an inch per dose for each cat when I notice coughing and regurgitation containing fur-balls. Always check with a vet in the case of unexpected sickness in your cats, but as long as you know the signs of fur-ball congestion, definitely try Katalax. I see improvement with coughing and regurgitation within two days worth of treatment and Katalax doesn't give my cats diarrhoea as other cheaper laxatives have been known to. It's a more gentle, but effective solution.
Unfortunately our cat has reached the stage were she needs Katalax constantly. Our vet was wanted to charge us around 23 pounds, which is a lot when buying it every couple of weeks. Thankfully finding it here for a reasonable price is fantastic.
Pity I wasn't aware of VetUK before purchasing the Katalax 20g from the Ark veterinary Surgery in Stratford upon Avon. Yesterday, I paid £20.05p for one tube. I won't be going there again.
Our old cat has occasional problems with Hairball if he slips under the comb and hides. This product is again wonderful. We had a tube in 2006 from the 'Vet' and recently used the last, so it's not often we use it. However, our vet charges £11.98 a tube so he has lost another sale. Thank you Vet UK value for money caring with us for our pets.
