Thanks guys. Tiger isn't doing too well. He seems to be getting enough air through his nose but he is making major rumbly sounds from his chest and some from his nasal area and is much weaker and wobblier. I had a new bottle of Transfer Factor compounded into a chicken suspension and of course he detects it in everything I tried to hide it in. For the past few days I've been forcing it in him and he resents it so much and it makes him cough alot and I don't want to continue with it. I know the cancer has metastasized (the vet informed me of this) and it is obvious with the chesty sounds he is making and I just don't know how TF will turn this around at this point. I do want to find a way to give it to him but forcing it is just a miserable experience. I don't want this last bit of time I have with him to be negative.
I have tried to hide the TF in the following things:

stinky cat tuna
canned salmon
canned chicken
canned ham
canned turkey
milk
baby food (ate it in this once but didn't want it a second time)
cream of chicken soup
Chicken a la King soup
gravy (for people)
gravy found in canned dog food
stuffed inside a pill pocket
yogurt
ice-cream
cool whip
sour-cream
salmon cream cheese(which he will eat but only every few days)
sardines and juice (" " " " ")


I'm going to try puree-ing some chicken and trying to mix it in there. I will also try some cream and maybe some sour cream and maybe some real whipping cream as opposed to the cool whip I tried. After that, I'm out of ideas.
If anyone has any other suggestions, I'd love to hear them.

In the meantime, here is a video I took of Tiger with his long time mate, Tiny. He used to spend 24/7 with her but she is very 'clingy' and for the past year he becomes aggitated when she is all over him which I can certainly understand. So, Tiger now bunks with Jimmy and Paddy and I let him visit with Tiny every couple of days. This is one of their visits (and a quick clip of Jimmy waiting his turn at the kibble bowl while Tiger is eating):
