I have the 125 Reef Tank
Son has a Teddy Bear Hamster
We have two cats
Spooky - 4 year old stray we broughtin last year (He has turned out to be the best cat I have ever had)
Zoe - 4 year old cat that we got after she had a run in with a car at 10 weeks old. She lost her front, right leg to that. We saw her just days after her amputation and she was chasing a huge dog and climbing a stair gate they put up to keep her contained. She had 18 staples to hold it all together afterwards.
Zoe climbs everything well. Spooky is afraid of Heights. I think Spooky fell out of a tree or something while he was a stray. Both are declawed now. Both seem to not care about the tank, although I think little one legged, declawed Zoe is responsible for the disappearance of more than one fish.
