Cole is our current rescue, he is only 3 years old but had cataracts in both eyes, and could barely see. Rescue spent almost $4,000 to get him lense implants. He did great, and should now be able to see the rest of his life well. He did well, though he had 7 medicines to take twice daily for 3 weeks, and had to wear the cone for 3 weeks. Daddy says when w go under the knife we get ice cream, but this was serious stuff and very expensive. thank goodness for rescue. he has now gone to a new home in Houston. if you want to adopt a Cavalier, visit the rescue site. Cavalier King Charles Spaniels.
