FFT2 and IFFT2

I have used imread to take a picture of kittens. I then run the fourier transform of the image using fft2 and then use ifft2 to get the image back. Unfortunately, instead of getting the image of kittens back, I am getting an almost entirely white image.
kittens = imread('practice_image.jpg');
fKittens = fft2(kittens);
reconImage = ifft2(fKittens);
figure, imshow(reconImage), title('Reconstructed image');
Thanks for any help
