My cat also has always spurned 'proper' cat beds - she prefers mine! As for cat blankets, sometimes she likes them, sometimes she doesn't.. she prefers the soft surfaces already available, like on the carpet or sofa. Which means muggins here having to deal with fur shreddage on a daily basis
Last night I washed my hair and left the damp towel near my desk. Earlier today and right now my big black tabby cat is laying snoozing on it. I have had cats who sleep in their own cat beds and a cat who used to spend much of the summer time sleeping in in shrubbery near the house I lived at then. Over time I have noticed the more money I spend on a individual item for either cats or dogs the more likely they are to ignore it.
Last time I was at the doggie warehouse (Pets at Home I think it is called), I noticed tents for cats. Yes, a little replica of an adult tent. So when you go away and spend the night in a green field, kitty can come along and enjoy the experience too!!!
How very ridiculous.
Which animal in its right mind would want to spend the night in a lonely little tent when it can snuggle down into the warmth your sleeping bag with you. And leave all its fur and nail bits in your tent.
