First of all, I will say that Hissie is staying overnight at the vet tonight. I will be picking her up in the morning. The vet gave her another enema. The vet called me and said, now all Hiss needs to do is grunt a time or two, then she will be relieved of this bout of constipation. So, Hissie is doing good. Forgive my ignorance about cats. Here I have been a huge cat lover my whole life and really knew nothing much about them. I just knew to feed their tummies, give them a safe home and plenty of love. But, thanks to you all, I have learned a lot and still learning. PrettyKitty, I now am understanding what you and the vet are saying about fiber. I will do all that has been suggested to me. I have just been so stressed out about Hissie and trying to absorb so much information on cats. But, I have switched her diet to Wellness. The vet tech told me, that Wellness was recently rated very high, among quality catfood. So, I have done that much right so far. I am understanding about the salmon oil as well. I will still give it to her, to keep her coat healthy. But, Hiss will most definitely be having fiber added to her diet, immediately upon returning home. Whether it is the husk, Metamucil, etc. Depends on what Hissie will take a liking enough to. BUT, FROM HERE ON, IT IS QUALITY CATFOOD AND FIBER. I feel very lucky that at 15, Hissie seems otherwise to be in good health. I got to believe Hissie is going to be one of those cats that may well live to 20. Wouldn't that be grand!!!! But, I am trying so hard to take good care of Hissie and do the correct things by her. Thank you all so much my friends for the kindness and knowledge. I will give an update on Hissie in a few days. GOD BLESS YOU ALL
