Petco

I know petsmart has the vets office in it so they should let you weigh them.

No

They do carry some rubber can lids for pet food. They have some in stock called the Harmony Rubber Can Lids.

No

No, they do not.

Some of them are tame and nice

Yes.

Anything with oatmeal

Yes butt if they have stroller in the store you want but its cheaper online, the store will honor the online price if you show it to them.

Prices vary depending on dog size and if you want anything extra.

Great question! It looks like they did the last one in January. If you are on Facebook like their page to get updates on sales.

Call pet helpers. They can give you numbers of reputable breeders.

Would recommend calling or visiting store and speaking with manager, as you will likely not receive an answer from staff here. However, as far as pest control goes, because they sell live animals, including insects, there are VERY few pest control options available that won't harm their animals or customer's animals. This holds especially true since you are stating one area is near live crickets, and pesticides would harm either the crickets or the pets they are fed to. Having visited this store weekly, specifically for crickets, bearded dragon supplies and turtle supplies, I've never personally seen these issues, even during my most recent visit.

No, they don't have any exotic birds

Yes they do
