I took Buddy to the vet's a couple of weeks ago as he had been scooting around on his backside and as he has been wormed I suspected it could be his anal glands. The vet confirmed this was the case and emptied them but only two weeks later he is scooting again

I've never had a cat that has had regular problems with this so am asking the knowledgable on here, how quickly do the glands tend to block up again - could they be blocked again so soon? Also, is there any particular food that is best to feed a cat who regularly experiences this problem?
Thanks in advance
