WHY ON GOD'S EARTH ARE THEY FEEDING THEIR BIRD CAT FOOD?!
Someone show them the pellets for birds, and compare ingredients... they may look the same, but they are not.
A parrot does not need that much meat. A little chicken and fish now and again, but not the kind of formula you would feed a cat.
And dairy is a no-no... they can't digest it properly. If they are going to give them ice cream then the only "safe" variety is a tiny amount (TINY!) of sherbert, or those frozen fruit popsicles... those also have a lot of sugar, but at least they can be fed as a VERY OCCASIONAL treat.
They are destroying this bird's liver... AND causing vitamin deficiencies.
Fruits, veggies, pellets, nuts, and a limited amount of seed... NOT beef chunks for cats!
