What is the equivalent for this Persian expression "The cat can't reach the meat, says it smells bad" [duplicate]

The expression, which implies the meat is placed on a counter too high for the cat to reach, is used when someone who can't achieve a position which is notoriously high or expensive, would pretend they don't like it. "Gorbeh dastesh be goosht nemireseh migeh boo mideh" Example: I don't like Ferraris, seats are too low. (said by someone owning a Fiat 500) Or: I don't like to own that $20M house up the hill, it's a long drive to get there.(said by a non millionnaire).

Thanks for the answer... "The fox can't reach the grapes, says they are sour." is an acceptable equivalent. Although in Persian it's used as an expression and a proverb exactly as mentioned above while the sentence with the fox is actually never used as is, but rather "sour grapes" as a reference to the fable. This is not a duplicate of the Jealousy question IMO. They are not jealous, maybe hypocrite. A duplicate is when the same question is asked. You can't consider any question related to jealousy as duplicate! I wanted to know the equivalent to that specific proverb and I got it. I hope the admin will not bury this inside a mass of jealousy related questions so that it helps others.

sour grapes

From Aesop's fable The Fox and the Grapes, in which a fox, unable to reach grapes it is seeking, convinces itself that they must have been unripe (therefore, sour) all along and so not worthwhile trying for in the first place.

Example sentence:

I think his comments about that new car are just sour grapes because he can't afford it.

(From Wiktionary.org, both quotes.)

There are many who pretend to despise and belittle that which is beyond their reach.
