Shift-click is only required to revive your pet while you are in combat, and then only if your pet has died and despawned since combat began. Under other circumstances, the addon is aware of your pet's status and edits the macro accordingly, but macros cannot be edited in combat. I'm always open to suggestions for improvement, but in this case I feel that the use of the shift key is a more elegant solution than button mashing.

Please post a bug report (just copy and paste in your previous comments on the issue) and I'll give you some things to try that should give me more information on what's going on.

1) Did your friend move an item in his bags, resummon his pet, or take some other action to trigger a macro update? Upon initial creation, the macro is not populated. This is something I should probably change, but as it should only ever be a "problem" once for any user, I haven't been very motivated to spend time on it.

2) Did you/your friend try with no other addons enabled? I'm not sure what would cause this problem, but I can honestly say that I've never experienced it myself, with any pet or food type(s).

I have a gorilla myself, and am not seeing this issue. Please try deleting the AutoPet macro, logging out, deleting and reinstalling Creature Comforts, deleting your existing saved variables for Creature Comforts, and logging back in. Open the options (type "/cc") and don't change any settings, but regenerate the macro by clicking the big red button. Drop it on an action button. Move something around in your bag to trigger an update. Does the problem still occur?

Notifications to people other than yourself will never happen. I would find it incredibly annoying to be grouped with someone who kept spamming party chat with "My pet is hungry!".

A sound option and/or support for additional output locations are possible. Please post a feature request ticket so I don't forget.

I've thought of it, yes, but every time I've recompiled my own lists, I've used LPT's lists as a base, and every time I've found many items that are missing, and even some that are incorrect. LPT doesn't auto-mine its lists of food items either, as per comments in its code, because Wowhead doesn't offer any filtering criteria to identify food items as anything other than "Consumable" or "Meat" (which actually means "cooking reagents" and includes things that aren't meat per-se).

I'm also not thrilled about the idea of having half of my addon's download size be one library that my addon will only ever use less than 25% of. If the addon is already strongly library-based, as FeedIt and Feed-O-Matic are, then adding 50kb in code for a food list and some unknown amount of CPU overhead to access it through layers of metatable and function calls is, I suppose, slightly less noticable of a waste, but it's not something I'm interested in doing in my own addon when a simple list table will do the job just as well. My philosophy on libraries is that if my addon will use less than 90% of the library, it's a waste to include it. There are addons that do use 90% or more of LPT, but mine isn't one of them.

Currently my own food list is less than 3kb and is cheap to access with simple table calls. And given that feeding is all but irrelevant in WoW 3.0, I don't really think it's a big deal if a few items are missing for a few weeks after the launch of an expansion.

Also, the version I posted a few days ago includes a full food database update.

There are probably quite a few new food items added in Wrath that Creature Comforts doesn't recognize yet. It recognizes food items by consulting a static list of item IDs that I've compiled, but since I'm pretty busy right now leveling four characters up to 80 and have about a dozen addons to get up to speed, I don't really have time to spend hours manually comparing my list to figure out what's missing. Obviously, I'll add any I personally encounter, but since my hunter will likely have to wait to level after my raiding main shaman and a death knight, it could be a while, so if you find any others, please post them so I can add them!

Sewer Carp is already listed, though. What happens when it's the only food item in your bags and you try to feed your pet?

If you find some spare time, find line 21 in Core.lua: if level > 0 then return end and change the 0 to a 5. Then, without taking any other actions, type:

/run CreatureComforts: Diet() (without the space before "Diet"; the "Disable smilies" option doesn't seem to be working here)

You should see it build the list of foods your pet can eat. On that list you should see "Basic Fish". After it's finished, type:

/run CreatureComforts:Scan()

You should see it scan your bags; this will be extremely spammy, but you should see it "Scanning ____ ..." on each item in your bag. For each item that is recognized as food, you should see "Considering ____..." followed by some information about the item. If the item is better than the previous edible food item considered, or if it's the first edible food item found, you should see "Accepting _____.", otherwise it will move on to Scanning on the next item.

Specifically, I'll need to know what it says when it scans the Sewer Carp. (Or the Underspore Pod, if it's still having problems with that.)

Everlasting Underspore Frond creates Underspore Pod, not Underspore Frond.

Looking at my code, I can't see any reason it shouldn't be including Underspore Pods in the list of things you can feed to your pet. What exactly is happening when you use the macro? Is it giving you the glowing hand cursor, or is it choosing another food item? If the latter, which food item is it choosing? When you're trying to feed your pet, what is his (or her) happiness level? Do you have the "Feed when happy" option enabled?

If your answers to the above questions don't give me any clues, I'll need you to enable debugging and get more information, so don't forget to check back!
