I have 4 feeders including one for the squirrels around the garden but I also have five cat visitors as I have a large planter of catnip. I am sure there are rats around but providing they do not get too close I am fine with that.
I stopped feeding the birds because of rats, two of them, male & female, boldly eating the bird food together. They look cute, but are classed as vermin, I don’t hate them, son had pet rats years ago & those were very sweet, but I had to think about the neighbours. So I stopped feeding the birds. After a few months I have started again, but no hanging feeders, no food on the patio, just on the bird table at present & so far no rats. It won’t last, but if I don’t see a rat I’ll carry on this way.
Most likely a squirrel destroyed your feeder as MrFraggle said.
There are squirrels here, but none have come into my garden for ages, without the hanging feeders there is nothing for them to get at. I have wire mesh around the bird table so only little birds can get in & squirrels can’t either & they have never tried, next door still put food on their path & the squirrels go there, I had seen a rat who managed to get on it some time ago. It was a baby though.
