im incledly sorry for your loss... after even a few mounths i lost my parakeet...i still havnt goten over it in 2008 for 30 years it must be hard. not to be rud or anything but next time i would sugest a necropsy, reson wye you said it was the first day out after winter there could have been posiens out there that killed your loved one that might do to your other pets. but please do not take affence im just speaking from experence, and it so hard to lose 2 more because i never had the first necropseid
