Ruby has not had real drastic drops , I get freaked when callie starts off with 400 ps and drops 300 points in 3 hours, the lowest callie has been is 44 at + 3.5 I just gave her 1/2 of ff with tip of a teaspoon of hc gravey and checked her in 15 minutes and keep doing so until you see 2 rising numbers , callie was at 47 at +7 this morning I gave her 1/2 of ff she was fine but boinggggg for ps , ECID but when callie go's low she acts no differently but will let you know she wants food !
