Christine Gardner described support from the clinic as "amazing"
A reduced-cost veterinary clinic has treated 160 pets in its first 11 days, according to the RSPCA.
The animal charity's Medway West branch has launched to offer cut-price care to the pets of people on low incomes or receiving benefits.
"Your pet would come first. You'd have a bit of toast yourself and pay out for your pet," said Chatham cat owner Christine Gardner. "Having somewhere like this is amazing."
She told the BBC it was "just really good to have something nearby that I can get to" with her six cats.
