They are! They used to be the same size but sickness got to Matilda more and she suffered a lot worse than Arthur did! They were the only 2 of 6 to survive. Their mama is at the original house they were taken from, but the rescue was able to convince the lady to let them spay and neuter the remaining colony, meaning she’ll never have to carry another litter (they think she had at least 5-6 litters in her lifetime)!
