You do raise a point.The one thing and reason why I personally would not get a long hair (I'm writing in case you do)....there's a rare condition where cats tummy cannot handle any amount of their own hair. My friend's cat had this and passed after two surgeries to remove bezoars even after diet change, brushing etc. If this does happen, the best thing to do is just shave them and keep them shaved. Now the vet didn't mention this and I didn't know. But now I've seen a few cats on social media with the same issue and their owners get them lion cuts.
Maybe this could happen with short hair cats too but Ive just not heard of it or it's not as bad because they well have less hair.
My Honey Bun swallowed a hairball and had to be liquid-fed a while till she could pass it. She's okay now, and fat and happy as ever. I try to brush in season to avoid too much accumulation of dead hair everywhere.
