Cattalkers: Is dead pigeon left on doorstep gift or threat?

I was out of town for a few days and my cat ran outside right before I was leaving.. My cat sitter was able to let her in the next day. Problem thawrted right?

First day back and I came back from work to a dead pigeon sitting on my welcome mat and Gabby acting unusually. Hyper a catch in her purr and hiccuppy. She calmed down and is now a little more clingy then usual but otherwise normal.

So firstly is she mad as hell and warning me to never leave again or is she just showing off her prowess love and relief I am back?

Secondly she didn’t eat it but pigeons seem to be especially disease carrying rodents. She didn’t look to be injured no visible blood or injuries quick body exam revealed nothing. The pigeon is about as big as her though, and I just think of them as disease laden scavengers so I am put off. While she has wrestled rabbits which were bigger I am wondering if she needs immediate attention. She has up to date shots. My cat guru is not available and I just have to know.
