My son had just turned 3 when we found our cat. She is now 19, and no longer a scaredy cat. People did not know we had a cat for over a decade! She still likes to hide, but is no longer ghost cat when we have company.
She is also MUCH more determined to sample humsn food. Till this past year, it was only my eating tuna that would attract her. Now, anything!
Kitty is not showing signs of slowing down, but I had no idea we might still have her another decade!
Both kids are out of the house now, (college and career) and she likes to hang in their empty bedrooms.
We adopted an elderly dog years ago and he basically told us when he was ready to go. Stopped eating, literally had a glory day and goodbye to the sunshine with entire family in the yard with him, and privately had a goodbye with each of us. Even Kitty. She has seen hamsters, dogs, a guinea pig, a lizard, mice, and fish, come and go.
If only I could translate her meows!!
