hey funny you actually started a thread about this.
my 5 yr old female, Skitzy is kinda fat, i actually thought she was pregnant so i fed her more. damn! now she really is fat. i ended up taking her to the vet for a check-up as i was worried about her, lol, i dont make her climb trees because of parasites and whatever else is on those things. but swimming. yes! i recommend swimming, so far shes lost an ounce, go Skitzy!
anyways my point actually is she has a triple chin thing going on, its looks kinda horrendus too.
oh and ive cut her food down now to one big mouse every fortnight.
good luck with yours
