Blood is thicker than tuna. Ralph
Below you will see that although Ralph loves his sister, he did not love the strange cat that appeared in the house last weekend who looked an awful lot like his sister but was DEFINITELY, 100% NOT his sister.
Luckily after about four days of this melodrama Ivy smelt enough like her old self for Ralph to remember that she cleans his head and keeps him warm during winter and sacrifices treats and lap space for his big butt and they were back to being best buds again.
