This life is not easy and when we lose people and animals we love it is harder. I choose to believe we will see our animals we cared for and loved ,again.
It is not clear and once we are in Heaven none of this may matter , but I know God loves all His creations.
Matthew 6 :26 Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not of more value than they?

All I know is God feeds and cares for them and they listen to Him better than we do. Any animal lover loves Isaiah 11:6-11.
There are not many verses to make it clear but in Montana I know I loved seeing wolves and one day they do not get in so much trouble as they do now for eating things man calls their own.
Isaiah 11:6-9
“The wolf also shall dwell with the lamb,
The leopard shall lie down with the young goat,
The calf and the young lion and the fatling together;
And a little child shall lead them.
7 The cow and the bear shall graze;
Their young ones shall lie down together;
And the lion shall eat straw like the ox.
8 The nursing child shall play by the cobra’s hole,
And the weaned child shall put his hand in the viper’s den.
9 They shall not hurt nor destroy in all My holy mountain,
For the earth shall be full of the knowledge of the Lord .
I see heaven in this so take comfort God has prepared a place we can not even imagine...
