I have three cats. Took Cat #2 and Cat #3 to the vet recently for a long overdue checkup, as Cat #2 have been eating messy for a while now (food all over the place) and Cat #3 had issues with her paws. Vet told me that Cat #2's teeth were horrendous and needs a serious cleaning (£650-850). Then she took a look at Cat #3's teeth, gasped, and said she needs to be scheduled in asaptually as it'll likely include some pulling because her teeth are in a much worse state (£800-1,000). I had no idea, because as opposed to Cat #2, Cat #3 was completely asymptomatic.The vet advised me to feed them dental kibbles like this after the cleaning surgery, but I went ahead with it immediately and hoped for the best (cause let's face it, ~£2,000 is a ridiculous amount to pay for cats' teeth).• I ordered the 3kg bag on the 5th of Nov (straight after getting home from the vet), it arrived via Prime on the 7th of Nov. I'm writing this review on the 17th of Nov.• The smell doesn't bother me, it smells like dried seaweed imo.• I am feeding my cats a mixed diet, wet food once a day, and leaving water and dry crunchies out for them 24/7.• Day #1: used the dental kibbles as treats (with great success!)• Day #2-8: mixed some of the kibbles with the remaining dry food I had left• Day #9 onwards: completely substituted their dry food for the kibbles, as well as mixing them into their actual treats.• I still have 2.3kg left out of the 3kg bag.Below are the results, with photos.• Cat #1 (Grade #1 Periodontal)7yo and I have acquired him a year ago only. Based on his behaviour around food, I believe he was fed human food regularly and, due to used to be an outdoor cat, he must've had his fair share of hunting and crunching on rodent-skeleton/bone. His teeth are decent, but did start to deteriorate in the year he's been with me. Nothing tragic and irreversible, in fact the slight plaque build up he had is now almost completely gone.• Cat #2 (Grade #3-4 Periodontal)9yo indoor only cat, and I have had him since we found him as a kitten on the street. His teeth are rank, but look at all the changes this kibble did on him already, chipping that nasty tartar away! He has a long way to go still, but I'm hopeful his teeth will clear up on their own.• Cat #3 (Grade #4 Periodontal)My 11yo girl whom I had since a kitten too, indoor only. Again, I had absolutely no idea how bad her teeth were! Thinking about it now though, she has completely came off of the crunchies in the past year or so, only been eating wet food, presumably due to the pain. I took one of the negative reviews to heart, and was initially incredibly stressed about her chocking on it - which thankfully did not happen! She only consumes the dental kibbles when I give them treats, every other day or so. However, even her teeth have improved ever so slightly! Whereas I do believe I'll need to take her treatment to the chin, I'm hoping I'll be able to improve her dental health until then, to curb the costs.Ps: if any of you reading this and are in similar shoes, check PDSA's/Blue Cross' website, as you may be eligible for a free or lower cost treatment.Edit (Day #20): I caught Cat #3 chomping on these now aside of giving them hidden in the treats! I'm ecstatic! They must all love the taste, because they're polishing their bowl in an amusing speed, regardless of 2 out of my 3 are most definitely in pain with their teeth!I'm therefore likely having to buy the 3kg bag on the monthly basis, which is pricey, but I much rather this than having to put them under for surgery.
