Do you have a scale to weigh yourself? If/when you get to where you can pick her up, you can step on a scale with her then subtract your weight. Or if you can get her in a carrier, you could set the carrier on a scale and subtract the carrier's weight.good. i'll tell you something stupid.
i gave her less breakfast this morn n it really hurt me
Doesn't sound like she's fat if you can feel her ribs. You've been giving her 3/4 tuna cans of food 3 times a day. How many calories is that per day? I guess you'd have to know how many cups of food she's eating.
