premise: Last night we had finished the eye drops for the kittens although one of the kittens looked like he needed ongoing treatment . So this morning we went into town to buy some eye drops to help out our little man . When we were at the vet we soon discovered that the drops we had bought last time were unavailable , however we could buy the same thing in a no name brand . These eye drops happen to cost two euros less and this made me a little annoyed . Why did they put eye drops in the kittens ?
hypothesis: Because they cost two euros less .
