Spider/Normal Growin up

Thanks for the comments!

Before I got her she was owned by someone the breeder had sold her too that went into the armed forces. Which is how I got her. But I don't really know their feeding pattern. I feed her a small rat every 7 days and have since I pretty much got her. I think if she is healthy then its not a problem if she doesnt weigh as much as others unless I was breeding her. But I've had her since the 24th-ish of July and she has gained 400 grams in less than 4 months, so she is gaining weight and all.
