Great product
These are great, I crush them and mix with some cats yogurt for my cat and a medium to long coat strays and it works you’ll see the fleas falling off and find dead ones. If you follow the three week life cycle of fleas and administer it once a week, and brush your cat regularly along hoovering/vacuuming and regularly washing all bedding and anywhere they sleep or rest it’ll also to break the cycle of infestation and keep your cats very happy 😊 I give this to my 15 year old cat who has feline diabetes and is insulin dependent and he tolerates it with no issues aside from becoming a bit excitable, itchy and warmer shortly after administering it which means it’s working. Overall I do like this brand as their other products have worked for me on all my animals since 2013 and the price is affordable ⭐️⭐️⭐️⭐️⭐️

Excellent and fast acting flea tablets
We got a kitten and seller said she had been flead. However, when we got her home poor thing was covered. Gave her the tablet and within 30 minutes she was going crazy scratching and licking like mad. Picked 2 off her feet straight away. Another 7 have come off her in the hour! Would definitely recommend these tablets. Will be buying agin going forwards.

Very effective and fast acting. Be prepared for drama and fleas to jump ship pronto.
The back of the packet says issue one tablet to your cat and that it may cause some distress for an hour or so as this product upsets the fleas. That is putting it in the mildest terms possible. My poor tom cat has always been susceptible to fleas in the summer months even though he doesn't even go outside anymore, he still somehow has them. Probably because he hates the drops on his neck and squirms relentlessly with claws flying whenever I have tried so they're probably not very effective. Likewise ambush tactics are the only way to get a collar on him, which he hates with equal intensity. I gave him one of these tablets and MY GOD! The drama was unreal for one, jumping and howling, in obvious discomfort. I picked him up and to my shock the fleas preferred to be on me than on him! To this these tablets are effective is an understatement, they little blighters hate it and will come to the surface so that a flea comb will easily catch them. Failing that the cat is probably now their least favourite place to be and they will seek someone else to go. That's why I also bought ultrasound pest plug ins which apparently discourage pests from settling elsewhere.

All four cats flea free but became very unwell!
Cat number 1. Had diarrhoea after drowsiness Cat number 2. Nervously running around for 3 hours with pupils dilated and panting Cat number 3. Scratching obsessively and then threw up her dinner Cat number 4. No appetite The next morning they all seem to be much better but there is another pile of bile like sick on the floor. One thing I will say is that it gets rid of the fleas but you need to make sure you’ve got something else in place as they will return as soon as the medicine wears off & I am not going to be using this on my cats again as I was scared they would all die. Look up flea bombs for the infestation (you must be out all day or for at least 2-3 hours , when you return clean all carpets, furniture, prior to bomb hide food/aquatic life/plants/makeup/cover furniture in disposable sheets etc. Your cats must also be away from flea bomb room until all the residue left over is gone. Flea baths! Dawn dish soap, vinegar. Let cat soak for 5 minutes and rinse. Small amount of garlic in diet! Baking soda on coat, let it sit for 5 minutes and brush out! Steam bedding and put all blankets on a high heat in the wash. Flea collars, Cat number 2 hates anything around his neck so this may not be ideal for all cats. Get yourself a human flea repellent as those little b@stards will bite you rotten once these tablets work if you haven’t done other methods alongside and if the infestation is large enough you will need it regardless. Lots of bowls with lights directed into them will attract fleas into it . Add fairy liquid in them & lemon (lemon will put cats off drinking from it and I’m pretty sure fleas don’t like lemon. Electric flea combs! Lastly collapse into a big heap and cry.

These work fast, and be prepared for your cat to go nuts for ½ hour - hour....but the fleas were literally falling off in front of my eyes, seems like a very good product, hopefully we will be rid of them for good!

Not for my cat
I thought I had poisoned my cat with these. He slept for nearly two days, and when he finally came around, he was still very lethargic and scratching himself. I suspect he was allergic to them, so I got rid of the two remaining tablets. I can’t recommend them because, even though they work on some cats, mine had a bad reaction.
