Is this healthy?

Hi
my female salmon pink tarantula has a serious fondness for dead mice
at first i was feeding her only on adult locusts black crickets etc but i was advised to give her the occasional mouse aswell so i dropped in a mouse and she flew at it . That was a year ago since then she will only take mice and even a small adult rat and nothing else, she ignores all types of bugs if they go near her she just kills them but leaves them? is this bad for her diet ive reduced feeding her a mouse to 1 large adult mouse every 3 to 4 weeks as these mice are quite big. she is huge and has a real chunky appearance.

There is absolutely nothing wrong with your parahybana, she just has found a taste for prime rib instead of burger, seriously though she is fine.
Some of the larger species eat vertebrates more than invertebrates as they get bigger, and then some like my big female Bolivian salmon pink [a chacoana] eat bugs as a preference

cheers mate ive no worriez then thanks

anytime buddy glad to help
