It says transmitting at a slant (satellite at horizon) at the antenna surface they measure ~1mW/cm2; the MPE for a person is 1mw/cm2 averaged over 30 minutes. Since a cat is much smaller, how does that effect their absorption? What effects could be expected (if any) if a cat were to sleep all night on the dish?
The only officially recognized effect of microwave exposure is heating. That is written into US (and probably other countries') regulations in black and white.
In actual fact, at low radiation levels, modulation is critically important. With judicious modulation, you can easily disrupt critical biological processes involved in growth and healing, at about any wavelength with very low power level.
But it is fairly unlikely that on a Starlink plate searching desperately for a satellite you would get modulation of a character to induce such effects.
Likewise your typical 5G phone or tower. But nobody knows, because literally nobody has checked. Actually checking would be extremely hazardous for anybody with any sort of stake in 5G or Starlink, opening them to various sorts of liability lawsuit for failing to disclose harm found, or failing to discover whatever harm is later found. Not checking at all, though, is A-OK!
So the experiment is being run on the general public, instead. Again. Happened with 4G, 3G, 2G, analog cell, each with its own modulation scheme and mix of wavelengths.
Cancer mortality rates go up, down, sideways, and nobody generally knows why.

Sources? Citations? Any particular reason why nobody is stopping cancer growth with software defined radios? (Or killing agricultural pests, or controlling malaria, or ...)
It’s non-ionizing radiation so would “only” cause radiation burns worst case. I don’t know what frequency the transmitter uses / how deeply the waves can penetrate, so you could also end up with “internal sun burn” as well external burns depending on the power and penetration.
This may be a cute picture but the real picture of the situation is rather bleak.
All wireless systems need power amplifier (PA) and most of real-world PA has much less than 50% efficiency. In any system that incorporates power amplifier, the power consumption of the PA is usually more than 50% of the overall system power consumption. If the antenna is further up the line, roof or tower, then the actual power it deliver at the antenna is probably less than 10% of the original power supplied to the PA due to impedance mismatched, etc [1]. As of now, a single Starlink setup and installation requires about 180 watts of power and assuming the PA uses about the half the power consumption then it probably operating at 100 watts. I believe using the current setup most of the power is gone to waste, and only a few watts is actually being used for the transmitting and receiving the wireless signals.
Since now wireless systems are so pervasive due to popularity of 4G/5G cellular, WiFi and satellites perhaps it's good idea to estimate the amount of power wasted and fully being used for wireless transmission and reception globally. Recently, there is an article this year on HN that tells the story of remote radio station operator in Ontario Canada that has gone mostly off-grid by using solar because the cost of solar and battery storage systems have both decreased by approximately 90 per cent since 2010. However, it cannot goes fully off-grid due to the excessive power requirement of the wireless radio station's tower transmitter [2].
