<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've had my two rats for just under a year; one of them an albino dumbo, the other a hooded-dumbo. My hooded rat got very plump and heavy in the stomach, and I noticed the older one hasn't made as much of a growth spurt. Anyhow, my concern is the fact that my chubby rat, the younger one, has suddenly lost her mass and the firm belly.

My question is; could it be worms - to a)Restrict the elder's growth and b) Been passed to the fat one, resulting in her weight loss.... or has she simply over come some sort of constipation/baby fat loss...
<bot>: Older rat hasn't grown much; younger rat seemed to eat well, getting fat, and suddenly losing the weight - could it be worms?
