The Bible was written for and about people. There's no mention of any kind about animals in heaven. Any discussion about it is pure speculation with basis. I would like to think that there will be but it would be pure guesswork.
And the lions will lay down with the lambs.
Isaiah 11:6-10
6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox.
8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' 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, as the waters cover the sea.
10 And in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious.
KJV
Because the God of all creation will supply all our needs according to His riches in Glory, he will certainly provide us with the companionship of the animals of that creation if that remains a need. God created on earth what He saw as good. I would believe if it was good for earth, it is good for heaven also.
