I think that is the right thing to do, wait until you feel it is the right time to get another pet
My wife's father's little Sheltie (they got her the same day as we got Dazzle) passed away in her sleep. He said that he and his wife, both in their late 60's/early 70's didn't want to replace her. But less than 10 days later they had a Havanese puppy As it has turned out the puppy ownes them.

BTW, Don if you would like a few more little felines, we have a few to spare. We have nine barn cats and 4 of the calico's are pregnant. I can bring some down to you this summer. Good way for me to see the "T" and share my wealth.
