Based on true story!!!
My sister and brother-in-law had a cat and dog who were very attached to each other. My brother-in-law claimed that their rude goings-on caused him to lose his appetite while eating his dinner, but his girth would not seem to support that story…
Edit: I would just like to say, to clarify the record for anyone who may be reading this that my brother-in-law is much, much slimmer than many people.
The card version of this has a red heart in the background.
