Whiskey's tumor removals

Hi there! My name is Gizelle, I'm Whiskey's mom! Unfortunately, my perfect house hippo/land seal has two different tumors he needs to have removed (one mast cell, one of another type) - one of which has grown very large and is beginning to cause him general discomfort. As this is his second surgery, its a bit more costly, and its been hard to save the necessary funds in the timely manner he needs ): there is nothing / nobody I love on this earth more than Whiskey...anything anyone may be able to spare would be greatly appreciated and never, ever forgotten by us
