Thanks! I got it on Amazon, link below. Unfortunately it looks like it’s gone up in price by $10 but it’s great quality and my cat loves it!

I got a silicone brush that my cats love, so I brush the longhair cat at least once a day, and the shorthair at least twice a week. The brush gets lots of the undercoat out, and so far we haven’t had any tangles.
I say “so far” because the longhair is only a year old & we haven’t had a winter with him in a full coat yet. I might have to eat my words, but I taught him to like being brushed from the day the vet told me he was going to be a long hair cat. He was a feral kitten and it wasn’t obvious that he’d have a long floofy coat until the vet saw how long his tail fur was.

Honestly, no joke, try the standard Whiskas perfect portions pate wet food... it's the easiest food to digest and my cat who was suffering from UTIs now pees like a champion and never has bowel issues anymore.
You can just get the Tuna Pate version too...
Cheap to try anyway!!
