My wife and I purchased Kitty Caps last week. We noticed the caps coming off within 2 days. There are 2 tubes of glue included the inside the "kit". The active ingredient in the tube is "Cyanoacrylate", also known as "Super Glue". Here's the problem. This glue has a shelf life of 1 year for a 2 oz. container if unopened. The tubes included in the kit are 2 grams which = .07 fluid oz.. Smaller amounts may have a shorter shelf life. The tubes in my kit had a date code, in very small print of, j2005= January 2005. This product is 7 years old, considerably past its prime. We bought fresh "Super Glue", problem solved.

ATTN: PETS MART PURCHASING AGENTS---Contact your source and have them package the claw covers separately. Sell the glue, preferably "Super Glue" separately.
We have a "Pets Perk" card and enjoy shopping at your stores and your employees are always friendly and helpful.
This is a corporate problem, an easy fix and is a customer satisfaction issue.
Pet-Co and others probably have the same problem, be proactive.
