Here are some thoughts:1) The traffic issue with the pet business is definitely something to consider. 2) Some may differ with me on whether a pet business is an "essential business" and how it will do in the next pandemic spike, but that would also be a concern.3) Having three tenants in the building instead of two will also reduce risk.4) The buildout that the pet business does may not be easily used by the tenant that moves in after them.Hope this helps,

These are things that are very easily remedied and cost very little.
