Chanda - we had a litter born to a calico barn cat that was 3 orange males, 1 orange and white male & 1 grey white male. The one female died w/i a few hours (runt?other issues?) but the boys thrived! Our daughter wanted the grey/white one, but I didn't know until I'd promised him to Vicki (who still has him). So she took the orange/white male - leaving us with three that looked almost completely the same and if you saw only one at a time, I could not tell them apart. I would have to dig thru pics - I don't know when they were born - 2010, 2011 or 2012. The pics I have in online album start in 2013 - as fully mature cats.
Trying to name them & identify them was almost impossible. Standing in the feed store, trying to decide how to do so, I FINALLY bought 3 collars - red, blue & black. The 3 musketeers became - Mr. Black, Mr. Blue & Mr. Red. We replaced the collars a couple of times as they grew - we know the 1st blue one broke at the plastic keeper. Thankfully, they never were w/o their collars at the exact same time, so we knew who was who at the time,
In 2013, not long after I started the new job at the Spay Neuter Clinic (they had done the boys' surgeries at least a year previous), Mr Blue was struck by a car in front of our house, but didn't die. He was pretty badly injured and I took him to work with me fully expecting them to either put him down or let me off work that day to send me to a vet that could take care of him. Neither happened - both vets that day are cat lovers - we did minimal intervention (very affordable) - fluids, a drug added to the fluids to reduce brain swelling (can't remember what it was - in ponies we've used DMSO), a antibiotic in his one injured eye. It was touch and go for a couple of days - he lived in a card board box and went back/forth to work with me - so that his eye could be treated every few hours - he was very friendly - always purring and most often the techs would take care of it before I got to the back. Even the one vet, allergic to cats but 1 of whom had chosen to see how he'd fare, would check on him - getting him to sometimes purr loud enough u could hear him up front! Then he was fully eating, using litter box and enjoying his time in the house. His eye took over a year to fully heal BUT he can now see fine. Then final intro back to the "wild"... You can't even tell he'd had a smashed head or a severely injured right eye anymore. We caught it soon enough (I think I heard him get hit as I was leaving the house to go to work) that the few drugs that were used worked their magic along w/ cats' amazing recovery abilities (u kno - those 9 lives and all).
In December 2014 while in temporary quarters (they were in a covered 10x10x6 chain link dog kennel) Mr Red got out a last time and neither the property owners (Vicki, pony friend, & her hubby James) nor we saw him again
.
But Mr. Black & Mr. Blue are still our outdoor cats here in our new place. They lord it over the other outdoor cats - sometimes literally fighting with them (2 spayed females) and even tear into each other now and then. Mr. Black, believe it or not, usually takes the brunt of the beatings - wounds and stripped skin - while Mr Blue usually ends up the unscathed victor.
