So, recently I has started to have a lot of fun breeding my pets, however I keep running out of space. I do offer the pets that I do not want up for sale, but they don't seem to sell very well (I sell them really cheap because the price of them doesn't phase me, I just want them to go to a good home). However, do you guys recommend I continue attempting to sell them, or just release them (like what some people have done with the pets they have purchased from me)

Since you can always get them back later, I would say release them. Many pets don't sell unless they are themed or fit a particular niche (max stat, six vis etc..) and even those can be hard to sell. There are a great many pets in the system and that always makes it much harder to sell pets that don't have a particular gimmick.

However, keep in mind that if you are in the lost grove, or plan to go there (through the story line) releasing a pet after it is 42 days old will increase your chances of getting an nest from the LG areas.

I have the same problem. I recommend that you keep trying to sell them, but maybe make "selling" into a game, like pick a box, because if it's fun, more people will participate. I tried that once and I sold a good number of pets.

Some people also wil buy the chea pets just to release. So pricinghigher is a good idea, plus peopl e might think it's worth more :)

Just note that most peopl e dont'really want under 3vis unless it has a restricted trait set or is a themed or something.

Like most people above me have said, it's generally hard to sell non-themed, non-project pets. There's so many pets already out there, since many people breed a lot too, that getting a buyer takes a lot of planning and such. I'd recommend putting pets up for sale for a few days before releasing, since there's at least a slight chance of someone buying, but otherwise just release if you're tight on space and they aren't selling :P

What i would recomand is to first set those pets in sale untill they reach 42 days of ages and then releass them, if someone want one they will be bought and if not, well, keep an eye for egg notification in the LG. Obviously if you nead space just clean them up early. ^-^
