I just had to share this. My rescue mallard was quite lonely, and I know they're social birds. Considering I have no other birds, I wondered if maybe...just maybe, could he learn to live with cats? Perhaps gain a fur buddy it's worth a shot. Better than him being alone constantly. I'll be sure to update. Would be wonderful to see him coexist peacefully with cats; despite being 'natural enemies' and what not. He's very content having them visit his brooder. Takes to napping directly on the kittens; best nest ever.
