Push, Goodwill Ambassador

Push, Goodwill Ambassador

Push is our resident cat. He came to us as an orphaned kitten in 2013. One of our clients found him on a golf course with a seemingly broken leg. During his exam, he persistently “pushed” the technicians’ hands for optimum pets and scratches, earning him his name.

Push’s road to recovery started off bumpy with the possibly of a leg amputation in his future. The technicians and veterinarians nursed Push back to health, and his broken leg healed on its own- perks of being a strong, feisty kitten!

If he’s not napping in his cat tower, Push loves begging for dog jerky treats, greets clients and patients, and loves to investigate carriers as well as oversized handbags.
